Printing From Firefox

[TheVig]

So I've got a little bit that is compiled as exe so I can tell firefox to open document with that exe to print

Function PrintFile

Code:

Copy      Help

ARRAY(str) a
tok _command a -1 " ''" 4

run a[0] "" "print"

However when I use it, the file does print, but at least with a PDF and Adobe Reader, reader will open up an empty instance when complete. How can I avoid this from happening?
