in reply to Print a PDF from a script
This should be doable. The Win32::Printer modules should help you select the printer to send to if necessary. For printing, you could shell out to the command line for actual printing with system() or even backticks.
I don't know if you have tried command line printing with adobe acrobat, but I have never been able to get it to work. I even called Adobe's support line once and the person I spoke to said it wasn't possible. For command line printing, I usually use GSView/Ghostscript ( http://www.cs.wisc.edu/~ghost/gsview/get45.htm, http://www.cs.wisc.edu/~ghost/doc/AFPL/get811.htm). With ghostscript, you can actually specify the printer to print to on the command line which might obviate the need for the Win32::Printer modules.
Unfortunately, although I do a fair amount of this sort of processing and printing, it usually takes a little finagaling to get it working correctly.
Good Luck
