A damaged USB cable, a bad interface card on the printer, an incorrect interface type selected in the printer settings, or the wrong driver loaded on the computer can be the answer to your query why is my Epson scanner not connecting to my computer? The simplest solution is to check the drivers. Remove the current driver and download the appropriate one. Try rebooting your laptop, printer, and wireless router as an alternative approach. To check if your Epson printer is connected to your network, you can also try printing a wireless network test report from the printer control panel. You can print this report right now by pressing the Wireless button on many printers.
