This gives me some ideas. Experience so far is all failure on NetBSD, FreeBSD
and Linux, though in the case of Linux, maybe the Slackware version was too old.
Or rather, the package with that version of Slackware (13.0) might have been
Either hplip doesn't see the printer at all, or can't install the binary
plugin; I tried both Ethernet and USB.
I can try again with a newer hplip on the new computer. On the old computer,
where I built hplip 3.11.1 from pkgsrc-wip, it failed to recognize the device
even when I tried by Ethernet. This was with NetBSD 5.1_STABLE.
Maybe I could try again, this time checking the dmesg.boot or logging in to the
wireless router to find the IP address of the printer and giving that to the
I can also see if the MS-Windows software works with Wine (build on new
Ultimately I also want to try with Linux, which might have a better chance than
BSD (Net, Free or any other).
There is no assurance I will be able to install NetBSD on the new computer,
though FreeBSD 9.0-STABLE is successfully installed.
