Printers lose communications

By meltvn ·
HI

I have an HP 890c and 870 printers. The problem is that when they are connected to two separate computers they do not print. I receive a message that the communication has timed out between the computer and printer.
Some times the printers doprint a Windows test page and work fine for a few pages but then start with their trouble again?
The printers both print their Hp test pages OK. The one computer runs WIN98SE and the other WIN ME. Both are new computers Piii range. Could it be a cable problem, because it was bought after we had the printers, it however does not help changing them around. What also bothered me is that the printers does the same on an old Pentium computer it however ran on WIN 98? The printers was cleaned and serviced.

Thanks
MELT

Your PC is not a problem as far as the processor goes. Intermittent printing failures are, many times, not the printers themselves failing. Check to be sure that your cables are rated IEEE 1284 which are more capable of bi-directional communcations.These printers talk back to the PC. Try uninstalling the driver, re-booting, and re-installing the software that comes with the printers. This software contains a little more than just the driver files. Take a look at HP's web for the latest drivers. The software has a "setup.exe" to run.

Also, your cables should not be more than 12 feet, but there seems to be plenty of examples where more length isn't a problem. Make sure your cables are not near any type of motor or high voltage equipment.

Hope this helps

Ok, here's what I would suggest (as a former HP printer support tech):
1. Make sure that you have a direct connection between the printer and the computer, no data switches or zip drives or any other devices on the LPT port.

2. Try to find a "known-good" cable, one that a friend is successfully using for example, and test with a DOS print test. This is done by exiting from Windows to MS-DOS mode and using the command
dir>lpt1
It is possible that all the problems reside in the cabling.If this test fails with a "known-good" cable, then perhaps the friend might allow you to test the printer from their computer so that we have a "known-good" printer port on the computer and a "known-good" cable which could then point us to the printer or the computer port itself as a source of the problem. Once you have a successful print using the "dir>lpt1" test, you can proceed with testing in Windows.

3. In the printer properties under Start>Settings>Printers go to the "Details" tab, hit the "Spool Settings" button and "Disable Bi-directional printing to this printer". Set the "Spool Data Format" to "RAW", and click "OK". Back on the Details tab, hit the "Port Settings" button and deselect both choices there. Apply the changes.
3. Make a test document in Wordpad and print it several times. You can make this document by copying and pasting text from some other document if you wish. The purpose of this test is to determine whether the printer driver is functioning properly in Windows, rather than testing from some other application that adds another layer to the software puzzle.

If this is successful, but problems persist when printing from other applications, then the issue would be with those other applications and I would seek a solution at their vendors' websites.

Hope this helps.
