The patch doesin't break anything on my system with a PCL compatible laser
printer connected via USB:

 ulpt0: SAMSUNG ELECTRONICS CO., LT Samsung ML-6060 Series, rev 1.10/1.00, addr 2, iclass 7/1
 ulpt0: using bi-directional mode

The following message lines correspond to switching the printer off and
on again (with patch; no change at all to the driver without the patch):

 ulpt0: at uhub1 port 2 (addr 2) disconnected
 ulpt0: detached

 ulpt0: SAMSUNG ELECTRONICS CO., LT Samsung ML-6060 Series, rev 1.10/1.00, addr 2, iclass 7/1
 ulpt0: using bi-directional mode

Printing works fine (tested from OpenOffice via CUPS/ghostscript/PCL
backend).

System is an Athlon XP with VIA KT400 chip set:
