Files
For some HP LaserJet printer models (1000, 1005, 1018, 1020), the driver needs at least version 1.0 of the following firmware files, which are loaded when a printer is attached:
-
/etc/firmware/ulpt-hp1000 -
/etc/firmware/ulpt-hp1005 -
/etc/firmware/ulpt-hp1018 -
/etc/firmware/ulpt-hp1020
These firmware files are not free because HP refuses to grant distribution rights. As a result, even though OpenBSD includes the driver, the firmware files cannot be included and users have to download these files on their own. A port which can download and install the firmware can be found in /usr/ports/sysutils/firmware/ulpt.
