We have been using our Dimension E310 with a USB Epson printer for two years. The computer suddenly quit communicating with the printer. Installing a new cable had no effect. We installed a Dell AIO 922 multifunction printer/scanner/copier with a new cable. We can scan pictures and documents from the AIO to the printer with no problem. We still get a no communication error with the printer. So, it scans but won't print. The driver for the Dell AIO was downloaded from the Dell website directly into the E310. The usb cable has been plugged into every one of the USB ports on the computer with the same result. All of the other USB devices (mouse & keyboard) work fine. Any suggestions?
