[comp.laser-printers] Laser printer/BSD Unix set-up problem

mfaurot@irscscm.UUCP (Michael Faurot) (03/21/91)

I've got a most baffling problem getting a laser printer to work with
a Unix system.  The laser printer is a Texas Instruments Omnilaser
2015 capable of four different printer emulations including an HP
LaserJet+.  The Unix host is a Sequent Balance which runs a variation of
BSD 4.2.

At present the laser printer does in fact work with the Sequent and
can print, but only when using a TI 855DP emulation.  When any of the
other emulations are used--especially the HP LaserJet one--only
mangled text or garbage appears.  All print tests have been done
with standard ASCII text files only.  No special escape sequences
or graphics are being passed to the printer.

When the TI Omnilaser is attached to a DOS based PC all of the
emulations work just fine and therefore it would appear there is
nothing wrong with the hardware within the Omnilaser.

Since the Omnilaser will print with only the single emulation it would
seem that at least most of the settings being used in /etc/printcap
on the Sequent are okay.  The actual entry looks like so:

	laser|TI Laser Printer:\
		:br#9600:\
		:of=/usr/lib/lpf:\
		:lp=/dev/ttyi6:\
		:rs:\
		:sh:\
		:lf=/usr/adm/lpd-errs:\
		:sd=/usr/spool/lpd:\
		:pl#66:\
		:pw#80:

Also, just to see whether another laser printer would fare any better 
a true HP LaserJet IID was hooked up to the same tty port, using the same
printcap entry and it also produced garbage when a text file was
sent to it.  It is also know to be good, and works perfectly when
attached to a DOS based PC.

Please send replies, comments and ideas only through mail as I only
have limited access to a Usenet feed.

Many thanks.
