  From what C=E9sar told me about a patch for the USB driver, I suspect
  that the problem is that the CUPS 1.2 USB driver expects to read from
  the printer.

I was confused - the mail about the patch was from Yorick Hardy, not
C=E9sar.

I've added a patch to disable the use of the back channel.  If you've
tried cups 1.2.x and failed to print on a USB printer, please update and
try again, and let me know if this helps.  I don't want to report this
upstream until we have more confidence that we understand what's going
on.

Log Message:
Add patch to disable the use of the back channel for USB on NetBSD.
This is based on a suggestion by Yorick Hardy, who reports that it
improved behavior.  Without the patch, the cups usb driver tries to
read status from ulpt(4) (for most printers), and this results in no
output.
