Printtool STILL broken
Last modified: 2008-05-01 11:37:55 EDT
Printtool is still not detecting all local printers.
After upgrading 2 machines this weekend one now sees a local printer,
but the other doesn't.
This main server has been unable to print now for TWO releases!
parport errors are still being reported on startup. From messages:
May 1 12:18:38 neuromancer lpd: lpd startup succeeded
May 1 12:18:38 neuromancer kernel: parport0: PC-style at 0x378
May 1 12:18:38 neuromancer kernel: parport0: detected irq 7; use procfs to
enable interrupt-driven operation.
May 1 12:18:39 neuromancer kernel: Installing knfsd (copyright (C) 1996
May 1 12:18:39 neuromancer nfs: Starting NFS services: succeeded
May 1 12:18:39 neuromancer kernel: parport0: no IEEE-1284 device present.
May 1 12:18:39 neuromancer kernel: lp0: using parport0 (polling).
Setting the parallel-port to SPP in bios removes the warning, and the port is
detected. However I can't get any output.
Printter is Cannon 610 (the same printer does print whan connectted to second
Q: What should the bios setting be?
printtool works for everyone else (including your other machine), so I'm
expecting this is a problem with your setup.
Autodetection may not work if your printer does not support the IEEE-1284
standard (most new printers do, most older printers don't).
The SPP mode doesn't support IEEE-1284 checking, so the warning message goes
away because the probing isn't tried.
Does something simple like
echo "Linux" >/dev/lp0
(Trying to determine if it's a problem with the port or with your setup)
