Description
When printing to slow USB printers (such as many of the Canon PIXMA MP series), CUPS very often produces a timeout. This usually halts the printer mid-print and generates the following error message in the web interface and the logs: 'Unable to write 8192 bytes to printer!'.
The fix for this is to increase the timeout value when doing usb writes. This has been fixed in cups-1.4.5 but I have also included a patch for cups-1.4.4 (which is the version currently included in OpenWrt). This patch increases the timeout from 45 seconds to 5 minutes, which has fixed the problem for me.
A quick Google for the above error message will show that a lot of people seem to be affected by this bug (or at least were at some time in the past).
Note: for me this problem occurred using a Canon PIXMA MP500 printer.
PS: I have no idea on what milestone this should be...

This is a duplicate of #11945. Trac kept giving me database errors while submitting this bug, so I guess it registered it twice. See bug #11945 for the patch!
