First time I tested it, it successfully printed 3 jobs and than

time it successfully printed 5 jobs without disconnection between and
after.

I booted machine with this kernel but I didn't turned off/on the
printer. So, as was with kernel 3.19, printed didn't done even first job
although lsusb saying it is connected:

$ lsusb

But syslog output didn't changed from what it was before and after I
sent first job to print:

$ tail -f /var/log/syslog

Again I turned off/on the printer and tried to print. This time it
printed only first job and disconnected again:

Conclusion. I don't understand what's happening with this printer. Turning off 
USB-reattaching helps but not too much. No we can print mo jobs until printer 
will disconnect. Could the issue be in printer hardware? Some time ago it was 
broken and then repeared at the service center. So the only idea I have is to 
check it with windows computer. Any other suggestions?
Thanks.

P.S. So using /usr/share/cups/usb/org.cups.usb-quirks now is not
necessary as I understood.
