I can not execute "PRINT TO FILE" like before...?

I just installed a "slipstreamed" OS on my laptop. I used a program called FINALE 2010 which creates a .mus file... Before i changed OS, I used to just click PRINT TO FILE from Finale and this .mus file is transformed into .pdf and thus, i can just copy them to a USB disk and have them printed outside (since more internet shops have Acrobats or other PDF progs and can easily print the converted .mus) NOW, i can not get this command to work. Everytime i try, it says "i must install a printer first" (OK, I DON'T HAVE A PRINTER CURRENTLY)... But even before, i used to just "print to file" and the .mus file is converted to .pdf easily.... DID I MIS-TWEAK my services.msc? What RELATED-services should i make automatic or manual (i guess that included the spoolsv.exe---i turned it on alright) for me to be able to do it again? Many thanks!!!
