Re: How to test the LPT printer port?

How do you test to see if the LPT1 port is functioning in hardware?

There are various diagnostics around that use a loopback plug.
Those can be a problem if you cant solder one up.

The other approach is to boot something like a Bart PE CD or
knoppix CD and see if you can print from that. That eliminates
the XP config being screwed up etc.

Would LPT1 fail alone

Yes, that does certainly happen.

or would the serial ports or other devices go with it?

Not usually.

Can it be repaired?

Nope, but it isnt hard to add a parallel port on a
card if you have a free PCI slot. May make more
sense to use a USB/printer port adapter tho.

Intel D865PERL MB
HP Laserjet IIP Plus
Canon MP780
Windows XP Home SP2

My Laserjet IIP Plus printer stopped working on this computer
suddenly after many months of reliable service. When I try and print
anything the printer que icon in the system tray immediately shows a
red X and a balloon announces "This Document failed to print". Status: Error-Print. This
happens for every application, including "Print Test Page" for
the printer's properties under Printers & Faxes.
*I have connected the printer and the cable to another computer. They
both work fine.
*I have a second printer connected via USB. It prints fine from this
computer.
*I can't print to the Laserjet from a networked computer.
*Attempts to print from DOS prompt results in nothing. No action or
message. *I have deleted and restarted to reestablish the LPT1 port from device
manager.
*I have deleted the printer and reinstalled it.
*I have tried to start the spooler (NET START SPOOLER) from a DOS
prompt. *I have toggled all the port settings, one at a time, and restarted.
*I have scanned for viruses, spyware. Did a file cleanup (Temp files,
etc). *I have check BIOS settings and LPT1 is listed and set to Auto.
*I attempted a PrtScn while in CMOS setup using the Laserjet's
"FormFeed" function to print the ASCI dump. No luck.
Still no printer.

It seems I need a diagnostic to see if this is a hardware problem.
Does anyone know how to determine this?

Note: once, I simply reinstalled the drivers. Then when I tried to
print the test page the print que went into a kind of loop. Spooling
- stopped - spooling - stopped, that kind of thing, forever, until I
canceled it. Never did it again.
