It doesnt work on my local machines, even though I bought the "pro" version because my printer shows up as available. The company is non-responsive and have that sinking feeling I get around situations where my money has been nicked. Caveat emptor. Oh..."free" is nonsense as you have to purchase the equivalent of print-tickets to print to a remote printer.
