For me it seems that the USB CUPS backend has problems to communicate
with the printer.
The error_log does not show any errors related to the job. The filter
chain (driver, rendering, ...) seems to work perfectly. There is no
message of the foomatic-rip filter and the usb backend ending, also no
message for the end of the job. It seems that the USB backend waited for
a response of the printer and perhaps timed out after a certain time,
but the error_log was extracted earlier. Please try another test of
capturing the error_log of the job, but wait longer this time, until the
job gets into "Stopped" or disappears from the queue.
Also execute "lsusb -vvv" and "ls -l /dev/bus/usb/*/*" as soon as the
job is stuck and another time when it has gone into "Stopped" state or
disappeared from the queue.
You can try a workaround as follows:
Run
sudo usb_printerid /dev/usb/lp0
and see whether the output contains your printer's model name. If so, do
cupsctl FileDevice=yes
lpadmin -p <name of your print queue> -E -v file:/dev/usb/lp0
If not, try the same with /dev/usb/lp1, /dev/usb/lp2, ...
Now try to print. Does it work?
Note that this is only a workaround and only works reliably if you have
only one USB printer connected to your machine.
