How do you test to see if the LPT1 port is functioning in hardware?
Would LPT1 fail alone or would the serial ports or other devices go
with it?
Can it be repaired?
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.
TIA
I installed a Rosewill RC-302 PCI to Parallel port adapter card and
everything is working fine again - on LPT3.
That would probably prove that LPT1, the printer port on the main
board is dead. Meaning: no signal is being sent through the
connection. Can you test and repair a connection like that,
Depends on how its failed. If its just a dry joint on the connector
itself its pretty easy to test and repair if you can solder.
If you have managed to kill the ic driving it with static etc,
its not really feasible to repair and not worth the hassle.
or is it not worth the effort?
Really depends on your capability soldering wise.
If anyone here has any experience testing and/or repairing these things I'd love to hear
your thoughts.
I'm quite capable of doing it, but generally dont bother.
