I am not having any luck with Two-Sided printing using the WPS54G Print Server and my HP Deskjet 845c. I want to confirm that this is possibly a limitation with bi-directional capabilities with the Print Server and not a configuration problem. My HP Deskjet 845c allows me to create Two-Sided printouts. It prints the odd-numbered pages, and then prompts so that the user can flip the pages over and then print the even-numbered pages on the other side. Works great when the printer is directly connected to USB. When I try to print Two-Sided through the Print Server, I get the prompt right away (nothing prints); when I respond to the prompt I then get the odd-numbered pages printed followed immediately by the even-numbered pages. Is this a limitation of the bi-directional capabilities or did I miss something in the set-up? Thanks much!
