With HPLIP 0.9.5 parallel port is now supported. We recommend HPLIP instead of HPOJ for all locally connected HP devices.
HPLIP requires the ppdev/parport kernel modules for parallel support. If your device supports both parallel and USB use USB, generally USB I/O will be faster.

The parport module conflicts with HPOJ, be sure to remove HPOJ devices with "ptal-init setup". Please submit all HPLIP questions and feedback to the HPLIP forums.

For all USB and network connected HP devices use HPLIP instead of HPOJ.
The HPLIP project is located here. Please submit HPLIP questions and feedback to the HPLIP forums.

HPOJ should only be used for parallel connected HP devices. HPOJ and HPLIP can co-exist on the same PC, but they cannot access the same device. For example if HPOJ is configured for device "/dev/usb/lp0" then device "/dev/usb/lp0" is not available for HPLIP. Use "ptal-init setup" to add/remove HPOJ devices.

HPIJS is part of the HPLIP package. For more information see the HPLIP documentation.
