Network printer needs to be manually enabled after reboot

I've recently installed Debian Squeeze on a new machine, and decided to try out the default GNOME setup rather than attempt to do everything myself. I added a printer using *System > Administration > Printing* — it found my network printer just fine. However, when powering on the machine this printer is disabled. I have to go to the same dialog as above, enter the root password and enable the printer manually before jobs will be accepted. Any ideas on how to enable the printer automatically? Note that it's quite possible that the printer is turned on *after* the computer, if this makes a difference. Either way it would be nice if the computer noticed when the printer was turned on.
