I\'ve been googling for the last few hours now and can\'t seem to find an answer. I did come close with this question
I\'ve got an intranet site on my windows server run
In the past I've output a PDF from HTML (look at pisa -- python library for handling this), and then used shell_exec() to print the PDF.
Not very glamorous, but it works. Also, this was on a linux server, so I'm not sure about the capabilities of command-line printing on a Windows box.
