Paradox 7 32-bit with SP3 installed
Windows 98 SE
Two local HP printers (LPT1 and LPT2)

System has been working fine with a single printer for years. Added an HP
OfficeJet G55 printer the other day and now Paradox gives "Unexpected:
General Protection Violation" when go to Printer Setup dialog.

Doesn't matter which HP printer is selected as the default.
Tried un-installing HP OJ driver but did not help.
Tried re-installing Paradox 7, although did not un-install first.

Any help is much appreciated.

Sounds like you will have to figure out what files the new driver installed then
manually remove them and reinstall the older driver

Keith,

Before you do, what Brian suggests (which might be a huge job), try to
remove and reinstall the existing HP drivers. Windows will say, that the
driver is already there, and ask, if you'd like to reuse it. Say "No" at
this pont, thus forcing it to rewrite the system files related to the
printer drivers. It might happen, that the conflicting DLL will be
overwritten back to the stable version.

If this does not help, Brian's suggestion might be the only way out
(although a tough one) short of reinstalling Windows altogether.

Regards,

Dmitry Vulis

I've found that HP drivers are very buggy
In my case things are better when using Microsoft drivers instead of HP ones

If the new Officejet is on your network, set the default printer to the
Officejet elsewhere in Windows, then use Paradox's printerGetInfo() to see
what the printer's printInfo.portname looks like to Paradox.

If its "port" name is long (someone suggested 16 chars is the max), Paradox
will gag trying to open the Printer Setup dialog. Use the Windows Printers
applet to capture this port to a local printer port, e.g. LPT2:, and see if
that fixes the problem.

Both printers are on local, physical ports (LPT1 and LPT2).

WRT the drivers being bad, can other Windows application (MS-Word is my
standard test) use the new printer ok?

If so, have you tried deleting the new printer to see if the Paradox problem
goes away? If it does, then I have to suspect the problem is not with the
printer or driver itself, but with something in the Windows internal names
for the printer, driver, and port that causes PdoxWin's printer setup dialog
to fail. These values can be interrogated, successfully, from within
PdoxWin without opening the printer setup dialog. Let me know if you want
more info.

I think I finally have the problem fixed.

To answer your questions, MS-Word and other apps printed fine to both
printers. Paradox was the only one showing problems.

What seems to have fixed my problem was to reduce the number of fonts
installed. The computer had 800+ fonts installed. I got that down to 100 and
now all works okay.

I had tried reducing number of fonts once before but still got the Paradox
error... I'm not sure why it worked the second time...

Thanks for this update, Keith. Now I'm curious -- did the installation of
your new printer also install more fonts? Or did adding the new printer
just trigger the problem that was resolved by removing fonts?

Sorry I didn't respond sooner. Haven't been back here since things are
working.

The installation of the HP OJ printer did install some kind of font
management software, and maybe did install more fonts. I really can't say
for sure what triggered the problem. I do know, though, that the computer
had hundreds of fonts (maybe all 800) before the HP OJ printer was installed
because it had two versions of CorelDraw installed.

Aha! One of the usual suspects. Try to cut that down to 200 or less and
see if it helps.

Yes, that was the solution.
