I'd like to try a USB printer at some point. I assume that to have any chance at working it would need to support Postscript output. I've got 17 printers around the office but all are big workgroup-class devices connected via Ethernet, not sure if I have any USB printers anywhere, haha. 
Instead, plug in an ASIX Ethernet dongle and access your network printers that way; it gives me a way to connect to my HP inkjet, Dell WorkGroup and cheap B/W laser printer.:laugh1:
