I have spent days fighting this problem.
After adding new Windows 7 "updates" it wanted to reinstall drivers for my husband's printer (LaserJet P1006) on my desktop. I had no choice but to accept.
With the "new" driver, I can no longer use custom print documents in WordPerfect.
I've tried removing all the drivers and installing the full package, but Windows keeps wanting the INF file, but I have no idea where that is.
If I compare my husband's machine to mine, they are definitely using different drivers. How do I get back to the ones I want? They appear to be on my computer (windows\system32\spool\drivers\W32X86\3), but I can't figure out how to get Windows to switch to the old functional driver.
Thanks for the help.
