I have a Canon BJC-3000 USB-connected printer, and for some
reason it will quite frequently loose connection with the computer. I
donât know if it is my toddler messing the cables, a defective cable,
whatever.
It shouldnât be a big deal, simply taking the cable off and on
again does the trick as far as lsusb is concerned. The real, big,
hugely annoying problem is called CUPS.
The thing with CUPS is that whenever that happens, even if
lsusb reports the printer again, it complains about âPrinter faultâ or
something the like. Sometimes restarting it works, more often I have
to recreate the queue.
So I digged up a little bit and found out that hotplug should
do it. Thus I went to /etc/hotplug/usb/ with mighty GNU Emacs, and
created both a file named bjc3k.usermapâ:
canon_bjc3k 0x0003 0x04a9 0x1051 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0
âand a script called canon_bjc3k:
#!/bin/sh
case $ACTION in
add)
foomatic-configure -s cups -n CBJC3K -N "Canon BJC 3000" -c
usb://Canon/BJC-3000 -p Canon-BJC-3000 -d s400a1.upp -o PageSize=A4
;;
remove)
foomatic-configure -s cups -n CBJC3K -R
;;
esac
Only that whenever I take the plug off or on, it always
execute the add action, never the remove one. So it is useless.
ÂHints, ideas?
ÂThanks in advance!
