Description amitabha 2000-11-10 15:17:05 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.


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 ?

My /proc/interrupts is
  0:     496708          XT-PIC  timer
  1:      19275          XT-PIC  keyboard

if echoing into the lp device freezes the machine, you have some sort of kernel
Comment 3 Tim Waugh 2001-05-28 14:17:56 EDT
Does this still happen?  Do you have any PCI or ISA parallel port cards in the
