>Hm, the odd is, the pages are rendered, and then send to the printer. As far as I understand, the picture is rendered before preview and later send or shown. At least the GDI+ render events / methods of the listener are not called after the Preview is visible under normal use.

If you are right (i.e. pages are rendered by VFP the same way in preview as in the actual output to printer), and considering that VFP REPORT PREVIEW did not run up the GDI count, then it only means that the problem is in the OS (print spooler, print server, or printer driver ) (?!)


>>In my case, the GDI resources are exhausted regardless of the selected printer. I replicated the issue using multiple printers, including Microsoft Print to PDF.
>>I've read before the docs you suggested. It says that the issue originated with KB5000809 and it was fixed in KB5001565, but in my case I had to actually uninstall KB5000808 (after uninstalling KB5001567 that was supposed to fix it).
>>My suspicion is that there may be multiple bugs introduced with the KB updates attempting to fix the printer driver conflicts. The GDI problem could be one of these collateral bugs.
