My father has been successfully driving an HP DJ-840C (probably not one of the
most current models in the line) with Xy-3 and (an unmodified) Xy-3 driver for
the DJ-500 series. I have done the same at that location with Xy-4 and a
4-series driver for the HP-DJ, which is circa at least a couple years
later. I
can find out the specific driver names for you easily enough. While I'm sure
these Xy-drivers could be adjusted for better results with the later
DeskJets --
given a good HP reference containing the relevant control codes -- the
results in
both these cases were pretty good. We only noted one anomaly: an extra page
printing at the end of each print job, which consisted of just one brief
line of
PCL gobbledygook in the upper left corner. I believe an explanation &
cure for
this anomaly has been mentioned here more than once in the past, though I
have no
record of it.
