Hi,
Under DOS, Clipper was able to talk directly to the hardware layer
(printers, modems, etc). But WinXP has inserted a layer of isolation
that stops this. The software spooler now has the responsibility for
determining if the printer is switched on, turning it on if it wasn't,
checking ink levels (HP printers and others no doubt), etc.
