Hello, I have an HP business inkjet 1200 and it keeps printing a test page after each job. For 3 documents, there are 3 test pages among the tasks. I tries unplugging the power cable but nothing happened. The software is windows '98. Any solution?

Turn both your printer and computer off then after a few minutes turn back on. This should cancel the print job.

readjust the margins in the printer page set up just before printing

Some of print heads may be failed.First clean very well the contacts on the print heads and printer using piece of cotton and some alcohol.If not help look which color don't print and replace that print head.

Make sure you have the correct page size in the software.

I don't think this printer will allow you to print in the last 12mm of the page as it needs this to hold the paper while printing.

Normal 0 Could have a corrupt driver.
Disconnect the printer or at least be sure it is turned off. I'd do both and when the CD software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

If the printer is new, then maybe the printer catridge nozzle seals have not been removed and so the catridges are not being detected.

If it has been working before and then the problem starts, look at which light is blinking  because the paper and catridge lights are different. So check wich light is on and get to me for further instructions.
thnx

I have the exact same problem. 1 Page okay, then ****.

I have a solution that is very similar to that printed above.
I have tested it on five installations on the computers on my home network and an HP Business Inkjet 1100, and the PCs running Win XP SP3.
Step 1) If you are setting up the printer from the HP CD, decline the question where it asks if you want to print a test page, (this will avaoid the first print job before re-setting the dates).
Step 2) Reset your clock back to a year prior to the year when your cartidge expired.
Step 3) Print a test page, or two. Or a few pages from any application.
Step 4) Reset your clock back to the current year.
The printer now prints fine. Since I performed the sequence above I have been printing with the "expired" cartridges for a few weeks. I have printed on about 15 occasions over the past few weeks, amounting to about 50 pages. No problems so far. I don't know how long this solution lasts or whether I will have to go through it again.
I have gone through a few different "solutions", including a Registry hack that didn't work, but this simple solution above has worked every time on five different installations.
I did not need to turn the printer on/off, and did not need to re-boot the computers.
However, if I sent a print job to the printer before performing the sequence described above, and the printer gave an "expired cartridges" error, then I would need to turn the printer on/off to clear the error, and flush the print queue.

Are you using HP branded ink?
