OK. I have a new Epson L210 printer, a multi-function printer. But whenever I connect it to my Windows 7 64-bit computer, the only detected function of the printer is the scanner. There is no installed printer. The scanner is working fine. But I couldn't print.
I tried installing the several times. I made sure that the cable is intact and the printer's power is on. It gets stuck in the printer detection.
I also tried installing the printer driver manually by clicking the Add Printer in the Devices and Printers section in the Control Panel.
SFC /SCANNOW
from an elevated command prompt. When it is complete, reboot and installing again. Make sure you do not have the printer connected until told to do so.
