Comment 12 for bug 57801

According to the steps you describe on the forums this looks like a duplicate of bug #29050.
This bug was fixed in Feisty (cupsys 1.2.7-4ubuntu1), a workaround for Dapper and Edgy is to add ppdev to /etc/modules and then reboot.
Are you using Edgy or Feisty at this moment?
If you use Edgy do you still need to restart hplip with the above workaround?

cupsys (1.2.7-4ubuntu1) feisty; urgency=low

  * debian/cupsys.init.d: Fixed parallel port module loading in the
    init script, the "ppdev" module got only loaded when the "lp"
    module was not loaded yet (closes LP#29050).
