A colleague has just bought a new computer and is struggling to connect his
LaserJet 2100pcl6 (yes, I know it's old!). Because it only connects via an
LPT cable and the new machine doesn't have an LPT port, he's got hold of an
LPT-USB adaptor and plugged it into his USB port.

Windows XP Pro SP2 recognises it and prints a test page, but it won't print
anything else (such as a Word document). Under the properties he's selected
the USB port, and the print processor shows "WinPrint" and RAW data type.

Can anyone suggest what else he might be able to do to get this bloody thing
working, or is he going to have to buy a new printer?

Many thanks.
