on printer class search duplex

This is the code I use :

InstPrinter()
PrnLandscape() ;
PrnDuplex( IF(US->RPRTDUP2, 2, 3) )

I can't remember anymore why I am using it.

... way I solved this problem. I installed my printer twice. The first printer is defined to print one sided, the second printer is defined to print duplex. In the print preview you can change the printer. So you can choose if you want to print duplex from the preview or not. Good luck.

It is in source\winapi\printdc.c

Mr. Ford, thanks, is this a part of the TPrinter class, or is this just a function in fivewin. I will try it either way. I noticed also it becomes difficult to print Landscape, and Portrait in the same print job because if you preview the metafile switches to the last orientation call made. However ...

I think this is the function you are looking for.
