Hi,

Today I finished testing the rest of the models that should work with the
hpinkjet drivers.  The following can be added to the "successful" test list
above:
DJ8xx -- OfficeJet T65
DJ6xx -- OfficeJet 570, 600, 700, PSC 390

Keep in mind that even though I generally test with only one model in each
series, the results should apply to all models in that series.  Of course,
if anybody finds that not to be the case, then please let me know.  :-)
I also didn't test with the PSC 500, but it should be the same as the R
series (DJ8xx).

I managed to resolve the problem I was experiencing yesterday with the 570,
which actually applied to all of the models that use the DJ6xx driver.  It
turned out to be the exact same problem that Joe recently reported where
print jobs didn't come out after I rearranged the escape sequences that
ptal-printd sent before jobs.  This time, the hpinkjet code was the culprit.
The bug was in global code rather than in code specific to the DJ6xx driver.
I hacked one file in it to prevent it from sending the <Esc>E before the
UEL (<Esc>%-12345X) before the job.  The patch is available in a new section
at "http://hpoj.sourceforge.net/todo.shtml", and I will notify the hpinkjet
developers so they can hopefully include it in later releases.

Joe, since I had trouble getting the OfficeJet 600 to work, I was surprised
that you were successful.  I'm guessing that you were printing directly to
/dev/lpX instead of ptal-printd, because it worked for me when I did that.
I even tried downgrading to 0.7, and that didn't work either.

I didn't test the DJ6xxP (photo) driver, which should work on the OfficeJet
700 and PSC 300 series with a special photo cartridge installed, because I
don't have any photo cartridges, which contain black, light cyan, and light
magenta ink.  If anybody out there has either an OfficeJet 7xx or PSC 3xx
with a photo cartridge installed, I would be interested to know if the DJ6xxP
driver also works (after applying the above patch), and how the print quality
compares to the regular DJ6xx (non-photo) driver.
