Hi We have not seen a blank preview but shrunk previews where it seemed like the normal letter size page was printed, then reduced in size and then placed on a letter size paper. Found out it had something to do with windows screen scaling for better viewing. Users had changed the screen scaling in their settings instead of changing the resolution. I m not sure if that is the cause for your case but maybe related. Have you checked to see what the actual pixel width and height is of the generated picture?
We ve also seen text disappear due to hidden characters when stuff was copied into 4d write areas from Word but that was when Mac users were printing documents generated by windows users. Not sure if this helps any, I just feel your pain with weird cases like that Regards Costas > On Mar 6, 2020, at 6:02 AM, Peter Jakobsson via 4D_Tech > <[email protected]> wrote: > > Hi > > I was wondering if anybody had encountered this issue. > > 4D Write document preview (created using "WR Build Preview”) displays a > blank picture only on one workstation on the entire network (there are 8 > workstations).
