CutePDF writer is a great tool to print your pac display windows to a pdf. this will make it easy to save on your server when you get it happening.
Also for doing things automatically, there is a program called AutoHotKey (i reckon Ben has mentioned this before in the forums). its a macro program that will 'record' actions (keystrokes and mouse moves) and reproduce those actions when a certain key is pressed. its a great little program and we have been using it for about 5 years to do things in Opto 22 PAC Project (one really big job was to resize 1200+ pac display windows and move some objects around, with autohotkey it took about a day!!).
if you can 'record' a macro to open a PAC Display window, click 'File' then 'Print', you could use a variable from your controller to trigger an application in PAC Display. Sounds heavy, but once you get the hang of AutoHotKey you'll never look back.
I hope this helps
