HPLJ4+ will not print

Trying to be as brief as possible:

Fairly new computer (maybe 4 years old) WXP Pro, HPLJ4+.

We had a paper jam in the printer at work. I cleared the paper and am positive that there was no paper remaining, since the sheet came

out whole with no pieces missing. Nothing has printed since, other than two test pages later on; one from the computer and the other

from the printer menu. They both looked perfect, so it does feed paper and will print. I get no error messages, no nothing other than silence and accumulation of documents in the print buffer, which I delete right away after trying to print. This printer has pnly printed 9640 pages during its lifespan, so I doubt wear is the problem.

I brought a HPLJ5+ from home and plugged it in, No change. Bought an almost new HPLJ4 (only a few hundred pages printed) from eBay.

No change. The printers print fine from my laptop at home.

We were using a parallel (at printer) to USB (at computer) cable. Changed it, still the same. Bought a parallel card and installed it with its

driver and full parallel cable. No change.

The computer works perfectly other than this. M$ has decided that there is no direct upgrade path to W7, and our business database

program is not easily transferrable to another OS or computer. Their tech charges run into the 4 digit range for this, so if we can avoid

this solution, there will be smiles all around.

Y'all know of a fix other than a trip to the dump with this one and emptying the bank account on a new computer and tech support?

Thanks in advance.

Try a USB printer, get rid of the parallel port as a variable. If the connection is on a card in the printer, reseat that, maybe check for a firmware update for the printer and run that on the computer that it does print from.

There is no router or anything where the computers and printer are? Networking should solve the issue.
There is only one computer with issues printing to that printer? Did you try deleting all the printer drivers and installing them again?

Test pages work OK or did that also stop from the computer?

Do any of the printers have a network port? If yes, try setting up the printers an an IP printer on the computer, try that way.

Yes, just the one computer, stand alone. No network.

I did not try to delete all the printer drivers because there is an inkjet/scanner connected. I did delete all HP Laserjet drivers. I tried the 520, 540 (I think) 3050, and 8000 drivers (as per advice to someone else on another forum), as well as the Windows default HPLJ driver.

I tried setting it on the various LPT ports as well as the first USB ports. I bought a parallel printer card and cable, still nothing, so right now it is back to parallel->USB cable just to eliminate the card as a problem. Also, I plugged the cable into every USB port on the computer thinking that one might not want to print.

The thing odd to me is that the printer prints fine connected to another computer, just not this one. And this computer works fine other than it will not print.

It worked fine until a paper jam. I cleared the jam and other than one or two pages which printed perfectly, it will not even acknowledge a print command. No error messages, no nothing other than the program tells me it is not printing, and the document is stuck until I delete it.

Thank you.
