- Sometimes when I send something to the printer, it doesn't print. If
- I run "lpstat -t", I see that it is spooled, the printers are all
- enabled and the scheduler is running. Checking the printers themselves,
- I find they are all powered, on-line, loaded with paper and all that
- good stuff BUT NOTHING IS HAPPENING. This occurs about 2 or 3 times
- per week - just often enough to be a big problem, but not often enough
- to let me do much experimenting.
-
- OUTPUT FROM LPSTAT DURING PROBLEM:
- system default destination: dp80
- device for lp1: /dev/lp0
- device for lp2: /dev/lp2
- device for dp80: /dev/tty2a
- lp1 accepting requests since Mar 17 16:26
- lp2 accepting requests since Aug 28 17:57
- dp80 accepting requests since Nov 2 17:09
- printer lp1 is idle. enabled since Nov 23 13:12
- ^^^^^^^
- Why doesn't it say "now printing..." ??
- printer lp2 is idle. enabled since Nov 23 12:34
- printer dp80 is idle. enabled since Nov 2 17:09

- We have two similarly configured systems which both exhibit the
- problem:
- SCO XENIX 2.3.3 (Upgrade UFM - update M installed)
- 486 DX 33 MHz AST, 10 MB RAM
- 600 MB IDE Hard Disk
- Sankyo 525 MB tape drive, BusTek BT542 SCSI controller
- with Chantel drivers so we can use it without
- the GT version of XENIX...
-
- One system has an 8-port DigiBoard serial board,
- the other has an AST 4-port serial board.
-
- On both systems, we have 3 regular old dot-matrix printers (mix of
- Epson, Star and OkiData). Two are connected to the two built-in
- parallel ports, the third goes through a serial/parallel converter box
- attached to tty2a. The converter boxes say "IQ Technologies, Inc.
- Model Q00C".
-
- Some occurrences of the problem can be cleared by using /usr/lib/lpshut
- and /usr/lib/lpsched to stop and re-start the scheduler. Often
- however, the only solution seems to be shutting down XENIX. When I do
- this, I often get a little fragment of some earlier print job printed
- on the printer which is attached to the serial/parallel converter box
- AS THE SYSTEM IS GOING DOWN. This seems like an important clue, but
- I don't know what to make of it.
-
- When I originally set up the printers, I used "lpinit" and the "dumb
- serial or parallel interface" with a very minor modification: I added
- an option to allow suppression of the form feed between print jobs.
- Also, two of the printers use the "dumb serial or parallel interface"
- with an additional modification which consists of a filter to truncate
- excessively wide output. (Both modifications are to help us use the
- printers to fill in pre-printed forms...)
