I have an HP Officejet 5610v USB connected to a Toshiba Satellite L305D-S5934 with Ubuntu 9.10 and I also have the same problem. I try to power cycle the printer, disconnect then reconnect the USB cable, and click System -> Administration -> Printing -> right click the printer icon and check Enabled. The only thing that recovers this is to restart the laptop, but if after I do so I disconnect then reconnect the USB cable, then I would have to restart the laptop again.
It may be due to a problem with system-config-printer-udev:

apt-cache policy system- config- printer- udev config- printer- udev: git20090826- 0ubuntu8 git20090826- 0ubuntu8 git20090826- 0ubuntu8 0 us.archive. ubuntu. com karmic/main Packages dpkg/status

The solution would most likely be to upgrade to Ubuntu 10.04 which contains the newest version of system- config- printer- udev.
