4.3 multiple printers on same port

[brad at bradley.UUCP]

We have a printronix mvp printer with the IGP board.  I would like
to set it up so that we can have the printer do 10,13.3,15,17 pitch
on the same printer.  I have 4 different filters to do the print
pitch change, and for different printers listed in the /etc/printcap,
each with its own spool directory.  the problem is that if the printer
is printing 10 pitch and you send something at 15pitch either 2 things
happen. 1. the job 15 pitch doesn come off or 2. it goes to the bit
bucket and I never see (not even on the printer).

I did move one bit of code. in printjob.c that has to do with the
execlusive open with didn't seem to be called because before this
printouts would be printed at the same time.

I also put the spool directorys to the same (/usr/spool/lpd) and that
worked fine, but if the printer was sending something, your printout
would come out in that pitch.

thanks
