Red Hat Bugzilla – Bug 20657
Printtool freezes desktop
Last modified: 2005-10-31 17:00:50 EST
I have a Canon BJC 2000 which works perfectly with Windows. I am running RH 6.2 on an AMD Athlon. Whenever I try to run printtool, it freezes the machine so I have to poweroff to reboot (the power switch on the machine does not work). When it reboots, I am asked to repair the file system with fsck since it finds unattached inodes. I checked /etc/printcap and it contains unreadable characters. I delete that. This happens every time, so you should be able to reproduce it. I tried all the different canon drivers - for BJC610 and up. There does not seem to be a native driver for the 2000 (there does seem to be for the 4000 series). Can you suggest what to do ? I have installed the latest lpr update from RedHat. This is urgent since I work with tetex and would like to be able to print out my files rather than go through the process of writing to the DOS partition and printing from Windows. Thanks. By the way, echo "Hello world" > /dev/lp0 also freezes up the machine.
Ok - I did some more testing. I have attached some more relevant information below. The printer works fine from Windows so I don't expect that it is a problem with the printer. Can someone please help me figure this out ?

if echoing into the lp device freezes the machine, you have some sort of kernel problems.
Does this still happen? Do you have any PCI or ISA parallel port cards in the machine?
