Till Kamppeter says:

"Following some e-mail exchange with Mike Sweet I have deprecated the usblp
kernel module in Ubuntu and Debian, at least if CUPS is used as the
printing system.

In the Debian/Ubuntu package of CUPS I have switched over from getting the
usblp kernel module auto-loaded and using the usblp-based "usb" CUPS
backend to blacklisting the usblp kernel module and using the libusb-based
"usb" CUPS backend."

Title:
  Oneiric usblp no longer loaded when USB printer is connected

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  After updating from Natty to Oneiric my USB printer stopped working.
  It turned out /dev/usb/lp0 was missing. This appears to be due to the
  module usblp no longer being loaded automatically when the printer is
  connected.

  Natty:

  [  171.216266] usb 1-4: new high speed USB device using ehci_hcd and address 2
  [  171.688446] usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid

  [  171.689057] usbcore: registered new interface driver usblp
  [  173.109642] usb 1-4: usbfs: interface 0 claimed by usblp while 'usb' sets 
  config #1

  Oneiric:

  [  975.800030] usb 1-7: new high speed USB device number 9 using
