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 [SPP,ECP,ECPEPP,ECPPS2] 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 okir@monad.swb.de).

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 RH62 machine). Printcap: lp:\ :sd=/var/spool/lpd/lp:\ :mx#0:\ :sh:\ :lp=/dev/lp0:\ :if=/var/spool/lpd/lp/filter: 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 work? (Trying to determine if it's a problem with the port or with your setup)
