Why is my HP Deskjet 2540 printer not printing?
Make sure you printer has been unplugged for at least 60 seconds, and then plug the power cord into a power outlet. Turn on the printer using the power button on the printer. Turn on the computer and wait for Windows to open. Try printing again and note what happens.
How do I get my HP Deskjet 2540 to print?
Log into your router’s configuration or setup page. Find the printer’s IP address listed in an attached device or DHCP Clients section. Press and hold the Wireless button on the printer until it blinks, and then press and hold the WPS button on your router. Wait for the wireless light to stop blinking and remain solid.
