>>One of our clients got a problem when printing reports from our VFP 9 application. Instead of labels and text it prints boxes filled with the color of the font that is used on the label. So you see mostly black boxes on the printed report. It seems to happen only at one printer (Toshiba). They are using a Citrix client, and when they first print the report to PDF and then send the PDF to the printer it works fine, as well as printing from Office works fine as well.

Today we could "solve" this error. The strange thing was that when printing landscape reports (The frx file was designed as a landscape report) the black space holders did not appear, it happened only on Portrait reports.

All other applications (Office, Acrobat) did not have this problem, only our VFP application.

After lots of trying, the solution was to set REPORTBEHAVIOR = 80 just before the REPORT FORM TO PRINTER command (which is called from the report preview form) and after that set it back to 90.
Of course we still don't understand why that happens at this client, they use a Citrix environment, but it still does not explain why all portrait reports have those black boxes.
