The printer needs its firmware to be loaded from the computer everytime it is turned on or reset. If you turn it on while your system is running everything is OK. A script is started automatically to load the firmware into the printer. If the computer is booted when the printer is already turned on, the boot sends a reset to the printer removing the printer's firmware and because the printer is already on, later on when the UDEV subsystem is started, the printer does not send any signal to get its firmware again.
In Karmic this is fixed. When CUPS is started it sends a signal to the UDEV with which the connection of all printers is emulated and so all needed scripts get started. -- HP printer won't work after reboot, needs to get power-cycled https://bugs.launchpad.net/bugs/419679 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
