printer peculiarity/printcodes question

[Bill Vermillion]

As Jeremy Anderson was scratching "For a good prime call 
391581 * 2^216193 -1" on the wall, he suddenly said:

When you say it runs off three copies, does that mean it runs
1 copy for the length of the run, and then does it two more times,
as opposed to printing each copy 3 times in a row.

Even if the printer is not set to make multiple copies you could
inadvertantly be sending codes to the printer.   That would
be the case of you print 3 copies of each form in a row.

That wouldn't be a printer problem as no printer of which I'm aware
will buffer 300 pages.  However, if in a Unix type system a printer
job is interupted, the computer restarted, lp turned of and back
on, the system will see that the job has not finished and will
start all over again.  This would be the scenario to check
if you print 300 forms once, and then do the same thing two more
times.

You just weren't explicit enough for me to tell just how
the 3 copies were being printed.
