From project site: 18-April-2005 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. Actual Results: В результате пользователь должен знать, что программы из нового пакета HPLIP и пакета HPOJ не должены управлять одним и тем же устроством печати
