          HEWLETT PACKARD LASERJET, DESKJET, AND PAINTJET SERIES

    GRAPHICS MODES--LASERJET AND DESKJET

    The HP Laserjet is capable of printing raster graphics in 
    "resolutions" of 75, 100, 150, and 300 dots per inch.  UNLIKE dot 
    matrix printers, the lower resolution mode yields IDENTICAL print 
    quality; the same number of dots are printed in all resolutions.  
    The difference is in the ADDRESSABLE resolution.  For each 75 dpi 
    "dot" sent to the printer, 16 itty-bitty 300 dpi dots are actually 
    printed--a matrix of 4 horizontally by 4 vertically; hence it 
    takes 16 times less data to fill the same area in 75 dpi mode as 
    in 300 dpi. 

    Patternland supports all four HP modes and uses two alternative 
    methods for each mode--making 8 Patternland Graphics Print Modes 
    available. 

    In modes 0-3, Patternland automatically "magnifies" the image by a 
    factor of 8 and thereby avoids complicated "bit-level" computing 
    to create the image.  These modes are fastest.  In Modes 4-7 
    Patternland writes one addressable "dot" per Patternland dot; for 
    example, in mode 7, 1 Patternland dot equals 1 300 dpi HP dot.  
    The vertical and horizontal magnification factors apply to the 
    printout.  Likewise, the individual symbol numbers 1-16 create a 
    variable magnification factor of 1 to 16 per dot. 
     
    NOTES:  Raster Graphics must be printed in the default Portrait 
    orientation, so max dots are for an 8 inch print line.  On the 
    Laserjet, the user must confine her/his vertical range to the size 
    of the paper in use; otherwise the printer will overflow and issue 
    an error message. (The Deskjet/Paintjet are not limited if using 
    continuous paper.)  All horizontal vertical ratios are 1:1. 
      
           Modes:   0     1    2    3    4    5    6    7   8    9 
        Max Dots:   75   100  150  300  600  800 1200 2400  n/a  n/a
             DPI:   75   100  150  300  75   100  150  300
           Ratio:  1:1   1:1  1:1  1:1  1:1  1:1  1:1  1:1

    PAINTJET GRAPHICS MODES

    PaintJet graphics function similarly to the LaserJet and Deskjet, 
    however only two resolutions are available in two Patternland 
    methods:

           Modes:   0     1    2    3    4    5    6    7   8    9 
        Max Dots:   90   180  n/a  n/a  720 1440  n/a  n/a  n/a  n/a
             DPI:   90   180             90  180          
           Ratio:  1:1   1:1  1:1  1:1  1:1  1:1  1:1  1:1

    Modes 0 and 1 use the automatic magnification by eight method 
    described above; modes 4 and 5 are the "direct drive" modes that 
    access the most dots.  

    PAINTJET GRAPHICS COLORS
    
    The PaintJet supports a palette of 330 colors in 90 dpi (Modes 0 
    and 4), but only 8 colors in 180 dpi.  The 330 colors are created 
    by "dithering" (putting side by side) dots of the eight colors in 
    a matrix of 4 dots.  The PaintJet graphics palette can be set 
    using Patternland's color palette editor by supplying RGB values 
    given in the manual.  Alternatively, the palette can be set from 
    the current video palette by Patternland if AutoPalette is ON.  
    Thus by changing the EGA/VGA video palettes, you can automatically 
    create a new printer palette.  Remember that only modes 0 and 4 
    use the full palette.

    GRAPHICS MODE WEAVE DATA AND GRAPHPAPER--LASER/DESK/PAINT

    Beginning with version 4.1 PWS can print the threading/treadling 
    information in the graphics mode pattern draft.  PWS can also 
    interweave a graphpaper background at printing time.  (See below 
    for discussion of Laserjet text-mode graphpaper.)  Only the 
    "direct drive" modes 4 and above can produce graphpaper.  Modes 
    below 4 will ignore the graphpaper setting.  Weave Data and 
    Graphpaper are both selected from the main Weave menu.

    TEXT MODE PRINTING--LASERJET AND DESKJET

    The LaserJet and DeskJet are capable of very fine adjustments in 
    character and line spacing, and the LaserJet driver supports 
    numerous preprogrammed increments, plus the variable character 
    and line spacing options.  These determine the text mode sett. 

    The HORIZONTAL increment is a 120th of an inch, e.g., 12/120ths 
    would yield 10 characters per inch.  

    The VERTICAL increment is a 48th of an inch, e.g., 8/48ths would 
    yield 6 lines per inch. 

    Both horizontal and vertical increments are accurate to 4 decimal 
    places, e.g. you could specify a horizontal increment of 15.3423 / 
    120ths of an inch! 

    In addition, combined horizontal/vertical spacings are provided 
    with the <S11> and <S18>.  These spacings are exactly square and 
    designed to fill in all the gaps when the block character ASCII 
    code 252 is used.  The square spacing <S11> is 11.4 characters per 
    inch and works well with ASCII #252 in the default font: Courier 
    <FC>.  <S18> works well when the Font LinePrinter is selected with 
    <FL>.  You can put these commands in the Printer Recorder and save 
    them with the weaving to automate your printer setup. 

    You can also select top and left margins, the number of copies, 
    letter or legal size paper, etc. 

    GRAPHPAPER BACKGROUND FOR LASERJET TEXT MODE 

    Beginning with V. 5.0 PWS creates a full page of graphpaper 10 
    squares per inch when you print in text mode with the 
    graphpaper background option selected.  The line spacing is    
    automatically set to 10 lines per inch.  For other setts you 
    would need to use the LASRGRID program described below.  This 
    option is not available for Deskjet and Paintjet text modes.
    
    PATTERNLAND LASERGRID FOR LASERJET (TYPE <LASRGRID> FROM DOS)

    To produce graphpaper for text mode printing using other
    spacings besides 10x10 per inch, a separate program, PATTERNLAND 
    LASRGRID, is provided on the supplementary files disk.  With 
    LaserGrid you can print or download as a form a graphpaper 
    background with any spacing and highlight you require.  Five 
    preset backgrounds are provided: 10 x 10 squares and 18 x 18 
    squares per inch, both in portrait and landscape modes and 
    highlighting--and one 10x10 without highlighting.  These five 
    graphpapers are designed to be used with H10 x V10 and H18 x V18 
    spacing setups.  Note that other spacings will NOT match the 
    graphpaper.  In order to align the characters within the squares, 
    and so that the Title line sits on top in Formats 2 & 3, the 
    graphpaper begins 0.08" down vertically for the 10x10 options, and 
    0.04" down for the 18x18 options.  The beginning horizontal 
    position is 0 for all four options.  THESE FIGURES WILL BE USEFUL 
    if you use the sixth LaserGrid option: a Custom Grid.  For 
    example, you could make the graphpaper only 5" x 5" square instead 
    of 8 x 10". Include the LF (linefeed) command in 
    Print/Define/Setup if you use Formats 1 or 4.  This will push the 
    pattern down one line onto the graphpaper. 

    MEMORY LIMITATIONS:  The size of the graphpaper your LaserJet can 
    produce depends on the number of squares per inch, the area of 
    graphpaper, and the amount of memory installed.  The preset 
    options 1-4 were tested on a LaserJet Series II with a 1 meg 
    memory upgrade installed.  The 18-square graphpaper is only 6 
    inches on each side because out-of-memory errors occurred in 
    multiple copy printing of larger areas.  If your printer cannot 
    produce results with options 1-4, use the Custom Grid option to 
    reduce the number of squares per inch or the area to be printed. 
    You will probably also want to consider adding a memory upgrade to 
    your LaserJet. 

    YOU MUST RUN LASERGRID BEFORE WEAVE SIMULATOR.  Then print from 
    Weave Simulator in text mode only using the characters you select: 
    the block characters <252>, <127>, and the <space>, <*>, and <x> 
    are especially useful. 
    
    Note that LASERGRID is a  utility program which will simply stop 
    with an error message if your input does not match what is being 
    asked for: e.g., you CANNOT highlight every 8.5 lines, but you CAN 
    set a square spacing to 8.5 per inch.  If you make an error, 
    simply reload the program. 

    TEXT MODE PRINTING--PAINTJET

    The PaintJet is more limited in its ability to adjust the 
    character pitch and line spacing.  H10 (the default 10 characters 
    per inch) combined with the V9 setup option provide a reasonably 
    square setup for ASCII character 252 to create a Pattern draft 
    with numerical data.  A graphpaper background is not supported.
    Color Mixed Printing IS supported, however the standard PaintJet 
    330-color palette is NOT available in text mode so the Color Mix 
    Printer Palette is created by overstriking Yellow, Magenta, Cyan, 
    and Black up to 4 times (See Dot Matrix Help and Color Mix 
    Printing help).  Palettes created in this way are vibrant and rich 
    but do not match the graphics palette and do not allow for the 
    variation of hue available with the dithering method mentioned 
    earlier.  Also, the video palette can NOT create a Color Mix 
    Palette for text mode printing. You must use the Rainbow printout 
    option to create a color key chart containing all possible mixes 
    and match the color to the video palette yourself.
