#2 WM_DEVMODECHANGE message

[Knut Martin Tornes]

I'm trying to use the DLL to change the printer
orientation. The orientation gets changed OK (if I check
the printer settings in the control panel), but applications
like Word and Notepad ignores it. I used WinSPY to see
if powerprinter sends any different WM_* messages than
when I manually do the same operation in the printer
settings. To me, it looks identical. What can be
wrong.....???
