I figured that much.
Anyway... there’s probably a solution to your issue out there somewhere.
As for me, if I need to print from afar, I can email the document to someone near the printer and they can print the document. I can’t think of why I would need to print to a printer that doesn’t have a human nearby.... but I would love to be able to print stuff on the White House’s printers.
How do you get by ISP size limitations? Some ISPs reject emails as small as 8 MB. There are services such as Gigasize, YouSendIt and Dropbox, and VPNs, but for many people Cloud Print would be simpler.
