HP Laserjet 4000 printing single pages

I have a HP Laserjet 4000. It is shared via a Netgear PS101 Print Server. It prints most things fine but when it prints multipage .PDFs it prints one page at a time; i.e. prints a page pauses, prints the next pauses, etc.. My other printer on the network is a HP Laserjet 2100 which has no problems with printing multipage .PDFs.

Two questions are they both connected to the PS101?
How much memory is in the 4000?

What version of pdf viewer are you using and when is the last time you updated your driver for the 4100?

got mixed up change the 4100s to 4000. More or less the same printer

jonoakley thanks for your help.

In answer to your questions:
2100 is on a seperate HP print server
Both Printers have 8 MB Total Memory
PDF viewer Adobe Acrobat 4 (becuse of it small size)
Laserjet 4000 Driver name: UNIDRV.DLL; Driver version: 5.00 - from a 'Print Test Page'
(I'm fairly sure that this is the latest since the last oficial driver released was in 2003). It has slipped my mind: how do I check the current driver of the printer?

In regards to adobe acrobat do you really think that getting a latter version might help. It has gotten quite bulky in the versions since 4 and I'd rather keep the older version.

I think that the 4000 will need more memory and I think I know how I can get some...

OK I also checked the settings on one of the users computers and it seems that the setup was saying that the printer only 4MB instead of 8MB.
(Properties => Device Settings => Installbale Options => Printer Memory) I've changed this setting and it appears to have improved the user's
performace a little.

Acrobat 7 is actually very good, faster than 5 or 6, also I have found that 4 often struggles with PDF files created in later versions.
Setting spooling to "start printing after the last page is spooled" will probably help, if you have a slow pc or network, as PDF files are actually postscript ddocuments, and rendering them to PCL takes a while.
It will take longer to print the first page, but the total print run will be quicker.

Just for what's it worth, we create PFD files off our unix server and then from time to time print them. Our HP5si is close to my desk so I use it  but after we moved our printers to a Windows2003 server the HP5si started taking an excessive amount of time to print a PDF but the 4000 and 8100's bang them right out. So I'm not convinced that memory is the total answer. I've tried all the settings and various drivers with no improvement.

Unfortunately, recent versions of Windows seem to take an inordinate amount of time to process Postscript documents, and the postscript  dll changed name from winnt to 2k for no apparent reason (renaming the old file to the new name makes it work).
Call me a cynic, but maybe the operating system is deliberately being "better" at GDI and PCL.(PCL being basically a text file with a header, it is difficult to slow it down).
I know that Adobe reader 7 for Linux is excellent, and prints fast to postscript printers, whereas the windows version is good, but printing is still slow.

In addition, disabling "advanced printer features" in the print driver>advanced tab often speeds up postscript printing for some printers. (and reduces the spool size).

Just noticed the reference to UNIDRV.DLL
That is the windows builtin "minidriver" which is a cutdown generic Microsoft table driven driver used for many printers.
It is not a driver for a specific make or model of printer, and is often spectacularly poor (to be honest, this is not MS`s fault), especially when printing to postscript printers.
If available, try downloading and using the manufacturer's driver for that model.

Thank you all very much.

I'm waiting on a bit of RAM to stick into the offending printer, then I'll see what happens.

I'll get back here soon.

MrBillisMeCommented:
I hope it cures it, if it does we'll try it on our 5si, too.

OK I've upped the RAM to 16MB total and changed the driver to the latest one from HP.com and it's a no go (sorry MrBillisMe).

That was still with Acrobat Reader 4. My next step is to try the latest Acrobat Reader and see if that solves the problem.

I'll do that then get back here some time soon.

P.s. I'm not too sure about the PostScript vs. PCL argument but I'm using the PCL 6 drivers for both HP printers.

MrBillisMeCommented:
Thanks for reposting,

I just realized our 4150's handle the PDF's OK, try installing the 4150 drivers rather than the 4000.

MrBillisMeCommented:
Well, we found a cure for our problem on the HP5si printer. This solution was offered by an on site tech guy that doing some programming in our UNIX server including the web interface. He was printing an 80 page PDF file to our 5si and didn't want to wait an hour suggested we try the hp3 drivers.

So we set up another printer ID on the network for post script and used the LJ III driver for that configuration. If we are doing a PDF job we choose that printer and it prints at full speed. The reason for setting it up as a second printer is because using the HP3 driver does not allow all the features available in the 5si printer. If we are printing a one page PDF or normal Windows job we can use our printer Q5si but for multi-page PDF's we use Q5pdf.

Works llike charm.

Give it a try

I've put on the new PCL drivers and updated Acrobat reader to 7. wyliecoyoteuk - thanks for your explaination on the UNIDRV.DLL

So you are sugesting that I setup the post script drivers (I think I'll try the 4000 ones first, then the 4150 if that doesn't work) and see where that get me.

So it might be the difference between using PS and PCL drivers?

wyliecoyoteukCommented:
PS drivers should print PDF`s better, as PDFs are actually postscript documents formatted for screen display, so you are using the native format of the file.
Does that model have postscript as standard? (not all printers support it, and some need an extra expansion card to do postscript)

MrBillisMeCommented:
Seems odd that your HP4000 has that problem since ours doesn't and we use the PCL5 driver, hope one of them works for you.

ProfWilliamWangAuthor Commented:
I've got the PCL 6 drivers installed.

Things seem to have imporved with the RAM, driver and Acrobat Reader updates - so I wan't put the PS drivers on just yet. I'll give it a little time to see if things are going well then I'll be abck to close this question down.

Thanks everyone for their help, here's hopeing for no more problems.

OK I think evertything is fine. Acrobat 7 and new HP specific drivers have help.

If I have any more problems I guess I'll give the PS drivers a go.

Thanks for your help.
