MultiPrint

SYNOPSIS
--------
{\Reformat -}
{\Justify -}
    MultiPrint <args>

      File/A/M
         :  Text file(s), to print and scripts of files to print.
            Can also include layout commands. See Later.

      TabSize/N/K
         :  Number of positions to expand tabs to, default is 8.
            This is only used when there is no justification, and
            paragraph reformatting is off.

      FF/S
         :  Pay attention to FormFeed characters. Starts new pages on a
            new column.

      Sides/S
         :  Print to both sides of a sheet. Only useful with cut-sheet
            feeder type printers, laser jets, HP Deskjets etc.
            See note on 'Last Page'.

      Font/K
         :  Name of font to use for text, defaults to LetterGothic.font
            See notes later on font usage.

      Size/K/N
         :  Point size of font, or pixel size if PxlFontSize specified.
            Defaults to 8 points (1/72ndsof an inch, ie 9 lines per inch)
            or 8 pixels (real small, smaller at higher printer resolutions)
            if you use Pxls.

      LineSpace/K/N
         :  Point/Pixel size of each line to print. ie Use twice the font size
            for double spacing.

      Columns/K/N
         :  Number of columns to print, 1..8. Defaults to 2.

      Gutter/K/N
         :  How many 1/10ths of an inch to leave at the left of odd, and
            the right of even pages. Defaults to 5, ie half an inch

      OddFooter/K
         :  Footer for odd pages, defaults to file name

      EvenFooter/K
         :  Footer for even pages, defaults to file name

      FooterFont/K
         :  Name of font for footers, defaults to same as Font

      FooterSize/K
         :  Point size of footer font, or pixel size if PxlFontSize
            specified. Specifying 0 causes MultiPrint to not print
            a footer, which includes page numbering.
            Defaults to 14 points (1/72ndsof an inch)
            or 14 pixels (real small) if you use Pxls

      Check/S
         :  Causes MultiPrint to do a 'dry run'. No printing occurs,
            but lines that are too long for the point size / number of
            columns combination are reported.
            NOTE: Only use this if you are trying to print a document
                  with no paragraph reformating and/or justification.

      Pxls/S
         :  Causes MultiPrint to treat font sizes as absolute pixel height,
            instead of point sizes. This method is dependant on the
            resolution of the printer, but is necessary for use with
            non-scalable fonts. If you specify this flag, you should not
            use the default font sizes.

      Priority/K/N
         :  Specifies the priority to run the spooler task at

      Ask/S
         :  Prompt for confirmation of each file to print

      Quiet/S
         :  No error messages for unfound files.

      Margin/K/N
         :  Space in 10ths of an inch to leave between columns.
            Defaults to 1 tenth of an inch.

      Line/S
         :  Causes MultiPrint to draw a line between columns

      Reformat/S
         :  Causes MultiPrint to reformat the documents into paragraphs
            as they are printed. See Later.

      Start/K/N,
      End/K/N
         :  Specifies which page to start/end printing on. Remember that
            many parameters effect page layout, such a font, font size,
            resolution, number of columns, footers etc

      Density/K/N
         :  Specifies the preferences density to use when printing,
            range 1..7. If you specify 0, you will be prompted with the
            dots per inch of each density. Not specifying density
            causes MultiPrint to use the current preferences density.
            See note on resolution later.

      LE/K/N,
      RE/K/N
         :  Specify edges of printable area, in _millimetres_ for
            greater accuracy. This is the only parametre specified
            in millimetres.
            Use 3 and 10 respectively on DeskJet 500s.
            See important notes on Page Usage and Environment Variables.

DESCRIPTION
-----------

MultiPrint is a program for printing text files to both sides of a page,
in  multiple columns, and very small, or very large, high quality fonts.

MultiPrint makes use of many Amiga OS Release 2.04 features, and so
requires at least this revision of the operating system. These features
include Compugraphic Scalable Font technology, to produce characters to
the correct size at the full resolution of the, printer, and the correct
aspect ratios.



SOURCE
------

The source code is not included, but is available from the author.
MultiPrint was writtern in M2Sprint Modula2, but should be easy to port to
other languages if desired.

PURPOSE & THEORY
----------------

MultiPrint was designed to print text files to as few pages as possible.
You know how sometimes having a .doc file is not good enough, you need to
be able to see it on paper, because you are always referring to it. Or you
have a really neat StarTrek© parody you want to show someone.

MultiPrint can print using multiple columns, both sides of a page, with
really small, but still high resolution fonts to fit many times the usual
amount on a page.

For example, an A4 page can usually hold about 60 lines of text. With
MultiPrint and an 7 point font (about 30 pixels high on a 300dpi laser or
deskjet) giving 100 lines of text, with 2 columns of output to both sides
of the page gives 100 * 2 * 2 = 400 lines per page.

MultiPrint uses whichever font you specify, and can handle narrow and
proportional fonts to increase the number of columns you can print. Lines
can be wrapped around and right justified for improved use of space and
readability, producing newspaper like output.

MultiPrint allows a gutter for stapling sheets together. The default of
5/10ths of an inch is quite adequate.

MultiPrint determines page size, and resolution from the system. Page
oriented printers such as laser printers and Hewlett Packard DeskJets
specify their resolutions directly. Tractor feed etc printers must have
their lines/inch and number-of-lines set correctly to reflect page length,
but they don't work so well for both sides printing anyway.

MultiPrint queues the pages, and uses a child process to print the even
pages first in ascending order, then the odd pages in descending order on
the reverse sides.

Due to the queueing of pages, MultiPrint can use a certain amount of
memory. All pages are stored in memory as they are processed, also the
program requires a buffer for processing the pages. Text files don't
usually get large enough for this to be a problem on most systems these
days, and this is faster and easier than spooling off to disk again.


VERSION
-------

This is version 1.3 of MultiPrint. It does everything I need, but I would
like to give it a nice Workbench interface. This may, however, take time.

If anyone has any need for features other than those present, let me know,
and maybe offer suitable inducements :-)


STARTING
--------

MultiPrint is a Shell/CLI only program, and requires at least version 2.04
of the Amiga OS. All parameters, as described above, except for the file
name, have defaults and require keyword specifications to override them.

MultiPrint runs at a default priority of -1, as a good printing utility
should, though this can be changed with the priority keyword. Priority is
not overly important in some respects, however, as MultiPrint does not
busy-wait. If your computer is fast enough, and/or so is your printer
driver, you could well be waiting on your printer. Laser printers however
will more likely be waiting on the computer, and so MultiPrint will be
grabbing every available cycle, so leave at a low priority for background
printing.

Before printing a file, it may be a good idea to use the "Check" option to
determine how much line wrapping is occuring. Modern fonts are variously
weighted. A good, light proportional font can fit many more characters on
average than a heavy non-proportional font, so check if the current number
of columns and font size will avoid line wrapping. Too much line-wrapping
and you may end up wasting space with mostly blank lines.

MultiPrint can be stopped at any time with a <CTRL>-C, or the break
command. It runs unattended until the midway point, if you have specified
the "Sides" option. In this case, when it finishes printing the even pages,
a prompt will appear. Wait for the printer's buffer to empty, take the pages
in the order they fill up your tray (reversed) and place them back in the
paper bin, face up (for DeskJets, I'm not sure for other printers), and hit
'Continue'. When the program finishes, the pages will be up the right way,
and in the correct order.


ARGUMENTS
---------

As described at the start of this document, plus

Layout Commands:
You can precede file names with flags to control layout. These are
specified as a plus (on) or minus (off) followed by the one of the
following characters preceding file names they are to operate on, and
stay in effect till specified again:

   C : new files begin on a new column
   P : new files begin on a new page
   S : new files begin on a new sheet (the default)
   L : new files begin on a new line
   N : restart page numbering after each file
 * J : following files start in Right Justify mode
 * C : following files start in Centred mode
 * R : following files will start in paragraph reformatting mode

 Codes marked as * are effected by the plus/minus. A minus to J or C
results in no justification, a minus to R turns off paragraph reformating.

eg. MultiPrint +J +R DocumentFile -J -R SourceCode.c

Script files:
You can print a list of files by passing a file starting with a first
line consisting of ";SCRIPT" (no quotes). Subsequent lines are controls
as above, and file names. If a file name starts or ends with spaces, it
should be quoted.

You can specify wildcards, but remember - MultiPrint does no analysis of
whether a file is plain text or not. Printing binary code can eat your
paper!

If FF is specified, FF characters start a new column.

The maximum number of columns is eight. Four is usually more than adequate.
If you have a need for more, let me know

Font sizes should be specified in points, which are 1/72nds of an inch.
This will result in the same size font on paper, no matter what resolution
your printer handles/is set at. See note on resolution.

However, if you don't have any scalable fonts, you may have to specify the
sizes of fonts directly. In this case use the "PxlFontSize" switch.

The "Height" argument is used to increase/decrease inter-line spacing. Use
a point size greater than the font size for a larger spacing, smaller for
less (at the risk of chopping the bottom off the characters).

"OddFooter"/"EvenFooter" override the default of using the filename in the
footers.

LAYOUT WITHIN A DOCUMENT
------------------------

MultiPrint is designed in such a way that you shouldn't need to modify
a document before printing it.

Sometimes, however, you might want to.

For example, there may be parts of a document where you don't want
paragraph reformatting to occur. Or you might want to centre just a
heading. Or you might want to use bold or italics for added emphasis.

MultiPrint recognises ANSI sequences for bold/italics such as are
recoginised by Amiga printer drivers, and by the console device, and
are sometimes used in documents.

MultiPrint also recognises some sequences of its own.

These sequences begin with {\ and end with either } or the end of line.
They are of the format:
  {\Xy a}
 where 'X' is the first letter of the command, 'y' is the rest of the
command, and doesn't need to be present, the space is required if 'a'
is present, and 'a' is the argument.

They currently include:
{\Bold [+|-]}
Turns bold on/off. Default is on. DOES NOT TOGGLE.

{\Italic [+|-]}
As with bold.

{\Underline [+|-]}
As with bold.

{\Normal }
Turns off all styles.

{\Justify [+|-|=]}
Turns on/off. '=' means reset to this document's initial state.

{\Reformat [+|-|=]}
As with Justify, but for paragraph reformatting.

{\Font [fontname]}
Change font. Will attempt to change to the new font. The font will be
in the current style, so if you want it un-styled, use {\N} first.

If 'fontname' is not specified, returns to the default font as specified
on the command line.

{\Section <Column|Page|Sheet>}
Cause a break in the document. One of C,P or S must be specified and
causes printing to continue on a new column, page (side of a sheet)
or sheet.

NOTE: - for Justify and Reformat only.
Justify and Reformat only take effect at the start of a line.

If they are specified elsewhere, they are IGNORED.

If they are followed by the end of a line (no spaces), that line is
ignored, no blank line is output. This can be assured by leaving out
the closing '}'.


SPEED
-----

MultiPrint is not the fastest way of printing. It does, after all, print
everything as graphics. This however is the most flexible way, and allows
for the maximum amount on a page (if you can read small, high density
text). Let it run in the background, however, and you only need to do
anything when all the even pages are finished (when doing both-sides
printing).

I admit, some printers are so slow at graphics (for example old DeskJets)
that you may feel this method is pointless. Still, it gives you the
option.

For higher speed use a lower density, but don't use too small a font.

NOTES
-----

Resolution
----------
The lower the resolution you use for printing, the less readable a font
at the same point size will be. A point size of 7 at 300dpi uses a system
font size of 29 pixels high, at 150 dpi the same font is only 14 pixels
high.

Font Quality
------------
This ties in directly with resolution. Fonts are designed for different
purposes, and because of this can be of different qualities.

For instance, many fonts on the Amiga are designed as screen fonts.
As such they are limited often to small point sizes, and even the larger
ones may not look good when printed.

MultiPrint is designed primarily with high resolution printers, and
scalable fonts in mind. Most scalable fonts are designed to be used at
high resolutions, and have a lot of detail in them. They look very good
printed at 300dpi with point sizes as low as 7pt. This makes them 29 dots
high. If you have tried using these scalable fonts as screen fonts,
however, you will know that below a certain size, they no longer look so
good. Fonts that are to be used with low dot sizes, must be designed for
them.

The bottom line is this:
If you intend to print at resolutions lower than 300dpi, either keep
to a reasonable point size (at least 10 to 12) or find a font that
looks okay at whatever size you require.

You might have to rely on system (non scalable fonts) using the 'Pxls'
argument.

Scalable Fonts
--------------
MultiPrint tries to be smart with Scalable fonts. If you specify
italics, or bold, or both together, it will attempt to load the correct
font for that style, rather than letting the system generate one. This
results in far superior italics and bold etc at the expense of whatever
time is required to open these fonts. MultiPrint will of course fall
back to system generated versions if necessary. However, do try to
specify the base name for a family of a fonts if possible. For example,
use CSTimes where you also have CSTimesBold, CSTimesItalic, and
CSTimesBoldItalic.

Fonts in general
----------------
Should always be on your FONTS: assign path, and don't need to be
specified with the '.font' extension. If you specify a scalable font
by its full path, bold/italic versions will not be found. Instead use
'assign Fonts: "path" add' to add the path to your fonts assign.

MultiPrint keeps all fonts used in memory until it finishes, so you may
run out of Chip memory for fonts if you use too many. If MultiPrint
cannot open a font for any reason, it will continue using the previous
font.
NOTE: when I say Font, I also mean style of Font (bold, italic etc).

Paragraph Reformatting:
Paragraph Reformatting is very useful for fitting text files into narrow
columns, where they would either frequently wrap, or seldom come close to
filling the line.

In conjunction with right justification, or flushing, you get a very nice,
newspaper style output.

The problem with paragraphs is determining where they end.

In MultiPrint, paragraphs are broken up in two ways:
1. A line which begins with a space begins a new paragraph.
2. A blank line marks the end of a paragraph.

The only common method this misses out, is paragraphs which start at the
beginning of a line, with no empty line before them.

With such paragraphs, you can only tell if there is a break by the fluke
of how much blank space there is at the end of the last line.

Documents with paragraph breaks of this kind will need to have their
paragraph breaks manually modified before printing.

Page Usage
----------
Printers seldom print to the whole page. In particular, DeskJet 500
printers cannot print to the top 5 millimetres of a page, the last
two centimetres, the left 3 millimetres, or the right 10 millimetres.

In order to get the columns of either side of a sheet of paper to
line up, you need to specify the left and right edges of printing as
the LE and RE parameters. Use the environment variable MultiPrint.opts
to specify these once you have found them.

The best way to find these is to print a test page with Gutter=0, LE=0
and RE=0, with +R and +J before the file name.

Environment Variable
--------------------
MultiPrint uses an environment variable - MultiPrint.opts - to control
often used options, or user defaults.

This environment variable has exactly the same format as the command line,
so make sure you try anything you intend to put in it on the command line
first. Also, avoid putting anything that will be interpretted as a file
name in the environment variable.

Switches which are specified in the environment variable, such as
'Line' or 'Sides' cannot be turned off in the command line. Do not use
them in your environment variable unless you intend to always use
them.

Last Page
---------
When printing to both sides of a sheet, the last even page is printed,
even if it is empty. This is so the sheet is ready for the odd page.

Printing empty lines can be slow, depending on your printer and printer
driver. The printer may appear to be doing nothing for a while after
printing a small amount on the last even page, and the last odd page,
which is printed immediately after.

Both Sides Printing
-------------------
After all the even pages are printed, you will be prompted to re-insert
the pages, once the printer has finished printing (emptied its internal
buffers).

On a deskjet printer, the pages should be inserted as they came out of
the printer, face up, top of page closest to the print mechanism.
