I've looked in both the user manual and advanced manual as well as a little online. This is a friend's printer with which I have little familiarity. The modem went belly up the other day therefore no internet to his desktop pc. The printer would not print though it was usb connected to his pc. He has 2 PCs and one, if not both, print wirelessly as needed. Regarding the pc connected via usb to the printer, I assumed if wireless went down, the printer / pc would automatically print via usb even if "wireless" mode was selected. Do they not work that way? I couldn't find his printer settings which would allow the type of desired connectivity. I found multiple settings for the printer on both his pc and printer but none regarding connectivity using usb. I set it up a couple of years ago and as I recall, using the included disk, one of the steps was selecting wireless or usb. Surely the connectivity change can be made without the install disk. Which now leads to another question. If 2 computers are involved and the choice is only wireless or usb, and both computers have the printer software installed, can one pc run with usb to the printer and the other pc print wirelessly? Thanks.
