Hi Stefano,

Could you please send us the PS file to support (at) pdfforge (dot) org?!

Please run the print job once more, but this time do not finish the conversion with PDFCreator. Instead go to the spool folder and send us the PS file generated in Users > User name > AppData > Local > Temp > PDFCreator > Spool for analysis.

Many thanks
Sascha

Printing from all other applications is working perfectly?
