[help] Why my print jobs are slowing down ? (HP 9000)

P

Hello folks,
please forgive my bad english ;)

I Hope I'm in the good group...
I'm not very technical, so any advise will be welcome :)


My context :
once a month we need to print about 6.000 pages coming into about 20
files in PDF format.
Some files contains 10 to 50 pages,
others files contains 100 to 200 pages,
and there is a big file (23 MB) containig 3300 pages.
The pages contains just standard ASCII caracters, no graphics.

The problem is :
the first 4.500 pages are printed normaly fast in our HP 9000 series,
but the last 1.500 pages are slowing down more and more, the lasts
pages are printed one a minute !

During 3 years everything was OK, but for the last 3 months we
encounter this strange slowing down phenomen, without having anything
changed in our printing chain.
At first the 6.000 pages were printed in about 2 hours. it take know
about 7 hours to complete the process !


Could you have any idea of what is slowing down the printing process ??

Things to know :

- The slowing down phenomen is not located on the printer itself, but
in the preparing pages process.
When we clic on the "Print" Icon in Acrobat Reader, we see the
"construction" counter displaying the number of pages generated, like
"1201 / 3300" for example, the number of page generated increasing by
12 ou 14 pages a second.

Whathever the number of different PDF files we have launched, when in
cumulative we reach about 4.500 - 5.000 pages generated, the
construction of the pages begins to slow down, 8-10 pages per second, 6
per second, 3 pers second, 1 per second, 1 in 5 seconds... and ends
with about 1 page per minute !

This appear during the construction printing job process. During this
time, the printer may be online and printing, or may be offline, it's
doesn't change anything, the lasts 1.500 or 1.000 last pages are
constructed slower and slower...

- the order of the PDF files printed makes no changes.
Whatever we begin to print by the bigests files or by the smallests
files, it doesn't change the slowing down phenomen. When about 4.500
sheets are printed, the nexts begins to slow down dramatically.

- The PC where print jobs are launched is powerfull and don't seems to
be the cause of the problem.
It's a P4 3 Ghz CPU, 500 MB RAM, and there is plenty of free disk
space.
Windows XP, and Acrobat Reader 7
When print jobs are launched, CPU consumption remain very small,
about 3% to 5%, even at end, when the construction of the pages is 1
page/minute slow.
RAM used is about 240 MB at start, and 270 MB at end, there's plenty
of free RAM available.

- Our HP 9000 is on our 100 MB ethernet network. The printer is piloted
by our our main printer server, a NT4 PC hosting the HP 9000 driver
provided in 2001 whith the printer.



Have you any advise on what I can check to get ride of this very
annoying slowing down phenomen ?

I have no access on the printer server to check on it, but I think he
is the faulty point. Does it have any sence ?

My main objective now is to try to bypass totally the print server by
installing the HP 9000 Driver directly on the PC where PDF files are
launched and creating a new "network printer" on the PC, using the IP
address of the printer. Do you think it's the right thing to try ?


Thank you for you help.


Patrick.

What is the state of this machine? The NT4 print server? How is its
hard disk? It could be it is filling up, it may be worth looking at the
state of it, delete dead files, old tmp files, de-fragment it etc. Could
you get it to go for the 3000 page document first rather than last in
the print run.

Hello Thimoty, thanks for the answer :)

Unfortunatly I have no access on the NT4 print server, I cannot check
this machine myself.

However your answer confirm my opinion that this PC Print Server is the
trouble maker.
I will ask our admin team to verify how this PC works, and to do some
cleaning on it.

Do you think the driver of our HP 9000 on the print server is old and
need to be upgrated ?
Actually the driver used comes from the HP CD, stamped "2001".

Could you get it to go for the 3000 page document first rather

This change nothing at our problem, the slowing phenomen always appear
after about 4.500 pages were sent to the printer, not depending of the
size of the files printed.

If we start our 6.000 pages print jobs with the biggest PDF file (3.300
pages), all this 3300 pages of this file are constructed, and printed,
normaly quickly.
And the 1.000 last pages of other files, contained in small PDF files
(10 to 100 pages each), will be constructed slower and slower.


THIS is the very weird part of the problem : the slowing phenomen is
not depending of the size of one file printed, but by the total amount
of pages cumulated from various files....

Strange isnt' it ?

I am sure that Timothy is correct, this is almost certainly a server problem. I
suspect that either the hard drive needs attention, or the server is busier
than it was for some reason. The people that look after it may need to increase
the hard drive size if a clean and defrag does not help.

Ok Tony,

Our next 6.000 pages print process is planned next week.
We are going to make a preventive cleaning on our print server, and
then look carrefully on this machine when we will launch the print
jobs.

Thank you very much for your answers guys ! :)

Patrick.
