HP LaserJet 2300d duplex problem

Hallo,

I bought a HP LaserJet 2300d (with build in duplex feature).
My computer is running Windows XP and I have installed the Postscript
driver.

In the printer configuration is the duplex option enabled.
When I print a single page, the printer use the duplex option and I
can see that the printed collect the paper again for the backside
(which is empty).

But it is obviously not necessary because it is only a single page.

Is the printer not clever enough to understand, that it is not
necessary to collect the paper if the job has only one page?

Is this a configuration problem or the normal behaviour when I enable
the duplex option?


Best regards,

Stefan Schor

Stefan,

This is normal behaviour for the LJ2300. It's a cheap printer (you might
not think so, but it's true!) and HP's lowest-proces mono LaserJet with
inbuilt duplex and is designed for flexibility ratherthan speed.

Printers which are designed primarily for speed have additional hardware
in them which switches the duplex pan (the part that directs the paper
into the duplexer) when they can see a duplex print job with an odd
number of pages is being sent (1, 3, 5, 7 etc). This involves extra
intelligence in the firmware and extra hardware and is only usually
found on 50ppm+ printers.
 
I have a 2200, it does the same thing. I wondered the same as you at first,
but eventually just got used to it. I'm sure it does it by design (cheap).
Still beats the heck out of manually duplexing, though.

You can use PCL6 driver with this
printer instead of PS. PCL6 is faster
than PS on HP Printers.

If you can, you also add memory in
printer for faster printing.

But that's true, in this model,
duplex mode is slow.

Regards,
Christian.

Interesting,

Would anyone have any idea if a Lexmark T420D or Kyocera 1020D have the
same *feature* :-) I was looking at the above two and the HP.

Being honest I ve'never come accross this feature (or none of our
existing duplex printers have it although they are more expensive).

Hallo Christian,


the printer works fast enough, the topic was only the unneeded
collection of the printed paper.

More memory will not help.. :)

Hallo,

I understand, but I think it is independ on the hardware. I suppose,
it is a software problem (feature) of the printer. HP didn't make a
clever software for the cheap printer.

I would say, that it is a software problem because I can disable the
duplex feature in the windows printer driver. So the hardware works
in both modes which can be controlled via the printer driver.

All answers are the same... It is a cheap printer which is not
so clever...

You misunderstand me - the HP DOES have the capability in hardware to
switch between simplex and duplex printing but NOT IN THE MIDDLE OF A
JOB. Printer firmware is very complex, especially when you're working
on timings of firing the laser and keeping track of EXACTLY where every
roller is in the printer. If there is half a mm difference at any point
can cause a paper jam and each roller turns constantly at a different
rate than the others. It's not worth HP's extra expense to put in extra
electronics and hardware and then additional code to run it for such a
low cost printer to correct a "problem" that no-one cares about.

It's actually an extremely clever machine. Link it up to a network with
an HP JetDirect 615N network card, point a web browser at it and look at
all the stuff it can do. It's the same codebase as all HP's high end
lasers so what you're actually getting is a printer with all the
capabilities of a LaerJet 4200/4300/9000 but with a lower engine speed
and fewer hardware features.
