LJIIID w/HP PS cart. on a DECstation 2100

[Steven Parkes]

We're running our LJIIID using a true-blue HP PS cartridge on a DECstation 2100
using transcript.  There seems to be some difficulty with this setup:

1) 19200 BAUD : doesn't work at all.  Printer immediately comes up with an
   I/O Config Error on the front panel.  The transcript package logs the
   error from printer, but its completely garbage.

2) 9600 BAUD : prints, but comes up with the I/O CONFIG ERROR periodically.
   When this happens, the printer log file gets

		%%[ PrinterError: Miscellaneous Error ]%%

   Pushing `continue' helps some (it goes on) but the error reoccurs.
   Eventually, some sort of PS ERROR ## occurs and the log file gets

	%%[ PrinterError: Miscellaneous Error ]%%
	%%[ Error: undefined; OffendingCommand: 439m ]%%
	%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

   The position of this seems pretty much random -- the same PS can be sent
   again and may work.

3) 4800 BAUD : pretty much the same as 2), though possibly happens less often.

This seems to be unaffected by settings of PAGE PROTECT, AUTO CONF, or
ROBUST XON.  I've been running in DUPLEX mode -- I don't know if single
sided affects this.  The printer has a total of 5M.

Wonderfull printer, but this is very annoying.  I haven't been able to
figure out from the printer what the problem is.  I'm not sure if its
flow-control related.  We have another non-LJ PS printer attached to another
2100 and it has no problems running at 19200.

Any suggestions would be welcomed.
