Computer does not "see" printer

This is an interesting, mind-bending problem - the solution is not immediately
apparent.

My computer is a custom-made unit, using an ASUS CUV4X-C motherboard.
The OS is W98SE.
It has a 800-megahertz Intel Pentium III processor, 384 MB RAM, and two hard
drives (C: 20 gig; D: 40 gig) with all kinds of spare space.
The parallel port mode in the BIOS is set for EPP - it uses 378H/IRQ7 by
default.

A Mustek 600 III EP Plus flatbed scanner __was__ connected to the parallel port,
and a Canon BJC-4300 printer to the printer port on the scanner.
Both the scanner and the printer worked just great.

I bought a Hewlet-Packard "psc 1315 all-in-one", installed its software, and
connected it to a USB2 port. The unit works like a charm.
I removed the flatbed scanner (both physically and in software), and connected
the Canon BJC-4300 printer directly to the parallel port.

__Problem__: The Canon printer will not work - in fact, the computer does not
"see" it. It shows exactly the same kind of error messages whether the cable is
connected or not.
I have removed the printer software from the computer, and re-installed it. I
have removed the printer port (using the device manager) and re-installed it.
The "device manager" tells me that the "device (ECP Printer Port on LPT1) is
working properly".
I have changed the parallel port mode to "ECP+EPP", to "ECP" and back to "EPP".
I changed the IRQ from 7 to 5 and back again.
I have tried the printer, using the same cable, on another computer using W98SE,
__and it works__.

Thinking back a few years, when this computer was new, I seem to recall there
were issues then trying to get this printer to work with this computer. Beats
me how it was resolved at that time. However, this time I made no changes other
than installing the HP device and removing the Mustek scanner.


(Interesting sidelight: I have an older Canon BJ-200ex monochrome printer. The
computer does not "see" it either.)
Anyone up to the challenge of suggesting a resolution this one? Any ideas are
welcome!

Thanks!

If you have a NIC set to 360h, try setting it to 280h or 340h

I'm afraid I don't understand - pardon my ignorance, but how does a Network
Interface Card affect the parallel port?

The NIC usurps an address range, not just 360h,
and that range includes 378h, discombobulating the printer.

If all else fails try refreshing the port driver.

Hi John,

With Win98 I have pulled my hair out with similar problems dealing with =
printers. Years ago I did some testing and found a solution that has =
worked for me on several occasions. Although my page is written about =
"System Information" the solution should be the same. Back up you =
Registry first then follow these instructions and see if that fixes your =
problem.

Look for:
5. System Information shows I have a problem with my Printer Drivers.

I had one of those scanners...are you sure it was using an LPT port? mine
worked from a SCSI card with SCSI2 (?) connector which looked like a printer
port

John,

I had a similar self generated problem of that nature recently. It sounds as if
PlugNPlay hasn't had a chance to do it's thing. My solution was to unplug the
data lines to the scanner and printer. Power down and backup, PNP should
recognize NO such devices. Power down again, connect the scanner/printer data
cables and power up.

PNP should now recognize the new devices. I had to reinstall the HP scanner
software, buy possibly didn't have to had I known what I was doing.

This technique worked for me. Maybe I didn't have to Power down, but seems I
remember that's a different uprocessor reset than a simple restart--maybe not.
But you should power down when messing with the data lines at any rate.

GOOD LUCK!
Don

Thanks to Hugh, Laurence, SG, Haggis and Don for trying to help me out.
The issue seems to be with the cpmputer (ASUS) not with W95SE.

I've decided to simply dump the Canon printer - don't really need it anymore now
that I have the HP PSC unit.

Thanks again, guys!

John
