So I tried the HPIJS driver. I tried setting the output quality to “From
Printout Mode”, and since it had several color options, I randomly tried
“300 Color CMYK” and 600 BestColor CMYK" as well.
All printed the testpage in greyscale.
Since it is a brand new machine, I tried a direct copy of a color
page and it worked fine. Our IT person said he printed color from
his windows machine with no problems.
I think it must be the drivers. We couldn’t print in color from
a Ubuntu machine also using the 7345 driver.
The tar files need unpacking first. They contain readme and setup script files. Usually just a matter of running from a terminal, then configuring via CUPS web interface. I doubt that they’ll work for you, based on the bug report I linked to. YMMV.
OK – Since my color useage is small and since we do have another color
printer which I can talk to properly, I think I’ll wait till xerox provides a
driver for this Workcentre which is included in a Suse distribution (12.3, 13.1??).
