are you printing a windows or PDFCreaotor testpage or a testpage from your application/ a remote machine? You can set the logging level to “trace” in the debug tab of the application settings to get additional information on the cause of the error.
A PDF Creator test page is successful, but a windows test page is not. It’s like Windows and PDF creator aren’t communicating. When I open the log when set to trace it shows the data releated to the PDF Creator test page, but nothing for a Windows test page.
the PDFCreator test page will only convert an already existing postscript file to PDF without going through any printing/spooling. The Windows test page will go through the spooler, so it seems this is where it is getting stuck. When you print something to the PDFCreator printer, do .ps and .inf files get generated in %temp%\PDFCreator\spool ?
