Deskjet 970cxi

deskjet970cxi print duplex(two sided) from Openserver 5.04? I know how to
build the interface scripts, I just can't find anything other than the
windows driver that ships with the printer. The generic PCL command
document from hp doesn't mention duplex on the deskjet. There are duplex
commands for the laserjet, but they do not work with the deskjet, at least I
can't make them work.
help appreciated.

Strange you should ask that as I just queried an HP expert on the
same topic.
His reply is that it appears full duplex is supported only under
the Windows environment and for the automatic full-duplex operation
the system sends bit-maps to the printer. The duplex is done with
something other than PCL commands.
An insider at HP suggest he reverse engineer the Windows drivers,
which he attempted, and had no success.
His advice to me was to the HP 2250 - which is one great printer.
Considering my 970Cxi cost $279 and the 2250 is $699 and price was
a factor I have to stick with the 970.
We're both out of luck for printing directly from Unix.

Can the 970 talk PostScript as well? If so, then you could insert enscript
into the print filter. I have done this with a LaserJet 2100TN to have
different queues printing to different trays.

windows driver, with duplex set the prn file was 18000 chars with out the
duplex set the file was about 1000chars less, I put it over on the unix
opend each one with hd duplex.prn > duplex.dump; hd noduplex.prn >
noduplex.dump. Loaded each with vi in diffrent screens and toggled back an
forth and checked the difference. Right away I see the ESC&l2S and ESC&l4S
difference and there appears to be a some sort of unknown string of
characters with an unknown to me syntax being sent. Not documented either.
HP is unusally silent not answering emails about this topic. I called too
and the tech said no problem I'll email you PCL command to do such.
They email me a generic PCL command table with nothing about duplex, after
calling back being left on hold for 15 mins they directed me to a particular
place on the web, to leave an email support question. I did and got this
generic response directing me their web site for general support.
Also if HP wants you to use there printers in a particular environment they
will construct their tech manuals in such a way as to make it difficult for
programmers to use them in another environment. The duplexing feature of
the HP Laserjet 5 and above, that sells for 1500.00 3 times the 970 is
fully documented. Why whould everything about the 970 be document but the
one thing that makes the printer attactive to folks in business, duplexing.
Thanks for your response.

I guess I'll have to do the same to see what I can see.
I have an HP published booked called HP LaserJet 4, and one of the
nicest parts are the charts. PCL commands sorted by Parameter and
group show that the Esc &l with a #S parameter is Simplex/Duplex
print. Having those codes give me hope, unless they have a
combined driver so that if the printer doesn't understand the
duplex strings the other part does.
The other person - who is really excellent at this - who told me he
thought it was bit-mapped - didn't get a good answer from HP, so I
assumed the worst. If I hadn't been doing so much other stuff I
might have taken a look. I'll try to do that tomorrow of the next
day. Maybe we can figure this out yet.

And the only way that you can typically find out on the box that an
HP will work under Unix is to see if one of the minimum
requirements is DOS 3.x. If so you know it has built in fonts.
You have to go the web page and nose around but the PDF for the 970
does say it has built in fonts. Nowhere else do I find that.

"Attractive for business". If you go to their web page you'll see
the 970 is listed for home use not business. However at a
5000 page/month Duty Cycle listing it certainly is designed for a
busy home.
I talked with my favorite refiller of cartridges [Paul at
Inkusa.com - just a very satisfied customer], and he said the color
inks are different in the 970 - thinner as I recall. While the
color cartridge lists at about $49 - as opposed to about $29 on the
855C I just replaced - he refills them for the same price. In the
$14-15 range for color and in the $12-$13 for b/w. One reason I
stuck with the 970 was I had just gotten 4 refilled B/w back from
him.
Thanks for the info on the above. If there's only 1000 bytes
difference it might be easier to find out just what they are doing.
Again. thanks.

i believe some of the newer printers will also accept PJL (printer job
language) commands. based on documentation i have for a sharp copier
configured as a printer, using the PJL commands allows access to special
printing features not normally available without a driver which is usually
the issue when printing from either dos or unix.

would PJL(printer job language) commands work. i had to go that route to
change some print options when setting up a sharp copier as a network
printer.

does the 970 support PJL (printer job language) commands. i have used PJL
connecting a sharp copier with a nic to our network, and using tony's
printer script wrapper to echo the PJL commands to the printer.
according to the documentation i have, PJL is useful for dos or unix systems
where a driver is not available.
