I have an Epson WF2630 connected by wifi to my HP2010i computer 64bit. One day the printer will work absolutely fine and print with no problem and yet, another day, like today, it will show it is offline and will not print anything?
Why does it do this?
Have you closed the paper tray, where the printed page comes out? Some printers have a microswitch that detects this and puts the printer offline. The better printers tell you to open paper feed tray but others just sit there doing nothing!
