Windows 7: Parallel port (LPT) not working in 7

Parallel port (LPT) not working in 7

I've been using Windows 7 RC1 as a clean install.

The computer has multiple drives and I have on each something else installed (XP, 7 and Ubuntu).
I first noticed I couldn't print to my LPT printer in 7 (it works in XP and ubuntu). Then I plugged in some other stuff. Everything works in the other OSs but in 7 the parallel port doesn't seem to be working.

Any ideas? I'm stumped.

Google doesn't show any problems relating the parallel port and Windows 7. Drivers is the first thing I'm thinking. Can you find the parallel port in device manager (Win+R, type devmgmt.msc)? If it's not working, it should be under Other Devices with a yellow exclamation mark and may be called Unknown device.

I have a Brother laser printer hooked up to one of my machines via parallel port, works like a champ - even have it shared...

The trick is to get the parallel port driver from the manufacturer (or off of the CD that probably came with the printer) and load it in. If that doesn't get it installed, then go to the control panel, devices and printers, and have Windows 7 look for the printer. It should find it, but may not find a driver. Browse to the install folder and it should find the ".inf" file it need to do the install.
