After an upgrade (I don't remember which one, as I haven't printed
anything for a long time), CUPS stopped working. I thought the printer
was broken, but it's working fine on Windows.
CUPS keeps printing the below in error_log until I cancel the job:
D [11/Jan/2006:07:12:03 -0200] [Job 254] Printer using device file
/dev/usb/lp0...
D [11/Jan/2006:07:12:03 -0200] [Job 254] LPGETSTATUS returned a port
status of 10...
W [11/Jan/2006:07:12:03 -0200] [Job 254] Printer fault!
Hello submitters of this bug#347522, could you replace
/usr/lib/cups/backend-available/usb by one of
http://kmuto.jp/tmp/usb.tar.gz and see error_log with debug
option when you send a print data?
Because I added DEBIAN (kmuto) to debug line, You can find it easily.
It reports status number, error number and message of ioctl.
Details:
1. As you know, usb backend from CUPS 1.2 checks printer status before
sending data. This is done by using ioctl(LPGETSTATUS) API.
2. I noticed usb-unix.c had a wrong logic. When ioctl is failed by some
reasons (fatal or not), usb backend always report Printer fault!.
I believe it is fixed by modified backend I mentioned above.
3. For Felipe and Jose, status=10(HEX) means printer looks off-line.
Can you see any more messages in dmesg or syslog?
4. For Norbert, status=0 means success, so I think your problem can be
solved.
Although lkml thread is bit old story and CUPS has already fixed this
issue, I got a hint and knowledge from this. Thanks a lot.
Thanks,
