I had some printing problem, tiff documents were printed corruped - I've managed to solve this by using the command L_SetDisplayMode(DISPLAYMODE_HALFTONEPRINT, DISPLAYMODE_HALFTONEPRINT) and now priting are fine, but now viewing this tiff documents are in low quality so I decided to change back the L_SetDisplayMode to DISPLAYMODE_SCALETOGRAY but it's not changing vice versa once you set a mode its stuck as long as you run your application.
Any ideas how it can be solved ? Thanks.

I'm using ver. 14.5 on Delphi 6 developing WebActiveX Viewer.

To turn off a display mode, you must specify it in the flag position (first parameter) but not in the second parameter. This means if you only want to turn off halftone printing, you must call the function like this:
L_SetDisplayMode(DISPLAYMODE_HALFTONEPRINT, 0)
