I have tested PDFCreator and it work great.
I just have one question, is it possible to reduce the page size from A4 to A5 like in some printers (laser printers) in printer properties.
i have found a walkarround just for reference.
in printer i have set the page to A4.
I print to PDFCreator i set it to autosave to D:\teste.pdf
the script: AcroRd32.exe /N /T D:\teste.pdf PDFA5
i have another printer PDFA5 that has the page size to A5.
and that it. now i can scale the pages to any size i want just need to set the page size on the second printer.
Thanks for a great software.
One more thing i my case if adobe reder is not open adobe will still stay open after print and pdfcreator will get stuck until close reader.
To resolve that i used Acrobat Wrapper (acrowrap``)
