- I have been having problems with printers for some time now. All of them
- with PostScript printers and parallel ports.
- Things are great for small print jobs but given a reasonable load, the port
- just stops and the jobs keep queueing up. The only solution is to reboot
- the machine.
- On busy printers this can happen 1/2 dozen times in a day.
- I have tried all sorts of things to restart printing, but only reboot is
- the guaranteed method. In some cases I have to stop the indigo, turn it
- off, then cycle the printer, then when its idling turn on the indigo.
- Seems like the port gets itself pretty confused and hangs.
-
- I have tried all OS versions from 4.0.1 to 4.0.5F
- stopping / restarting the scheduler does no good
- /etc/init.d/lp stop/start is no good.
-
- This has happenned on at least a dozen indigos, One indigo finally stopped
- working on the parallel port altogether.
-
- The printers are Brother HL-8PS and QMS-PS-410 which do work fine on MACS.
- Is it a memory problem?, all machines have been 16M entry models.
- osview is typically giving only 1-2M free when running a basic session with
- no heavy applications running.
- Maybe a comms problem as it only happens on large jobs when the job
- possibly exceed the printers memory capacity,Handshaking maybe Xon/Xoff not
- stopping the data flow.
- But the problem lies at the indigo end I am sure.
-
- Any Ideas .. Thanx in advance.
