You know, I also made a PDF printing to my modem, not a printer, and I got the same .ps file, same PDF. You might consider using a default device.
About PrintToFile:
I was able to install and use it without first registering.
My original print to file PDF was 850kb. PrintToPDF created a file that was only 200kb, but basically the same quality.
You still have to change page set up for each file you want to convert, and you still have to open your chooser to change printers, but otherwise... I'm impressed!
(and yes, I couldn't upload my avie and was waiting for the fix, then kinda forgot. thanksies. :))
