1. Error Handler (EHANDLER.PS):
This is a downloadable PostScript file that will redefine the default error
handling on a PostScript printer. In addition to providing the error-
handling on a PostScript printer back to the host, this error handler will
cause the current page to be printed (with "showpage") in its current state
(any marks made prior to the error being triggered) and will also print the
PostScript error, offending command, and operand stack trace on the same
sheet of paper. This file should be downloaded once each time the machine
is rebooted, and is very useful for error tracking. If you call for
support, we would prefer that you have this file downloaded so that we have
a consistent starting point for debugging.
2. Timing Tests (TIMEPAGE.PS):
This is a downloadable PostScript file that will do accurate tests for
Postscript jobs. It may be used when optimizing your PostScript driver for
determining where processing time is spent. It uses the built-in usertime
PostScript operator. Note that in many implementations of PostScript
some of the actual imaging into the frame buffer is delayed until the
execution of the showpage operator, and takes place while the paper is
actually feeding through the marking engine. Therefore, in the timing
results from this program, there are two numbers given: one number
represents the amount of time spent just prior to the execution of showpage
and the other number reflects the amount of time actually spent imaging
during showpage. Note that this overlap in processing will actually
allow the PostScript program to run faster, since the interperter other-
wise spends much of its time waiting while the page is being fed through
the marking engine.
3. Serial Patch (UARTPAT2.PS):
This is a downloadable piece of PostScript which has only one purpose:
to fix an obscure bug in a particular implementation of PostScript. If
you are using a "LaserWriter classic" (version 23.0 of the PostScript
interpreter), you should download this patch. Otherwise, you may ignore
it. The patch fixes the bug mentioned in Appendix D of the PostScript
Language Reference Manual (the bug is related to serial communications on
the version 23.0 LaserWriter)
To use these on your PostScript printer:
At the DOS prompt (">") type the following:
mode com1:9600,e,7,1,p
copy xxxx.ps com1
If your printer is on COM2 instead of COM1 you should change the "com1" to
"com2" in the previous example.
