The problem is, printer at lp1 must be switched on while booting, otherwise system freezes after message "Starting cupsd". This happens with cups 1.1.19-100 (latest version SUSE online update supplied me). I reinstalled 1.1.19-75 from CD, and system boots with both printers off.

Thanks to Klaus for attention. I tried cups 1.1.21 as suggested but with no success. Also I have to correct my statement that 1.1.19-75 works, it works sometimes.
I am puzzled by the fact that only the 2nd printer must be switched on during startup, 1st printer can be off. Both printers are old fashioned parallel printers, USB is not into play.
Another distribution has no problem with both printers off, but has a more recent kernel. May be I have to live with this problem until I upgrade to SUSE 9.2 (or later).
Is there a way to prevent cups from scanning printers upon startup ?
