Thanks for all the hints. I have tried the following:
- Activated the interrupt mode in /etc/modprobe.conf by activating options parport_pc io=0x378 irq=7 - Removed the installed fax since my device doesn't support faxing anyway. In this way I got rid of the "second scanner"!? - Changed BIOS settings from ECP+ EPP to ECP Printing works fine but I still have the same problems with scanning. - Changed BIOS settings from ECP to EPP Again printing works but not scanning. The module ppdev is installed and loaded into the kernel according to lsmod. uname -a: Linux linuxserver 2.6.16.21-0.25-default #1 Tue Sep 19 07:26:15 UTC 2006 i686 i686 i386 GNU/Linux When trying to scan from xsane I get an error message "Couldn't allocate picture memory" when clicking the OK button a new message "Memory finnished". When trying to scan from Kooka the program crashes again. var/log/messages shows a line: Nov 29 14:09:03 linuxserver kooka: unable to fill data buffer: size=18411: prnt/ hpijs/hplip_api.c 450 This line appears both in EPP and ECP mode. To me it seems to have something to do with memory or memory buffering? Since I'm no expert I don't have a clue how to go on with error-tracking from here? My computer is equipped with 1GB RAM and the swap partition is also 1 GB. /Mikael Eriksson onsdag 29 november 2006 12:28 skrev Johannes Meixner: > Hello, > > On Nov 25 16:36 Mikael Eriksson wrote (shortened): > > Running HPLIP 1.6.10 on openSuse 10.1 for my parallel port > > All In One printer Office Jet Pro 1150c. > > ... > > > ... after a few minutes xsane report a "device I/O error". > > Perhaps there is an issue with the parallel port: > > There are some bug reports about problems with the parallel port > in our Novell/Suse Bugzilla.
