(I hope this is the right place to post this.)
I'm trying to print a document from my laptop, and at first it told me to enable bidirectional communication, which I did by checking the "Enable bidirectional support" box under the "Ports" tab in my Lexmark 4800's properties.
But now when I go to print, it just says "Communication Not Available, The printer cannot communicate with the computer., Try these solutions: Ensure the printer is powered on, Disconnect and reconnect the printer's power cable, Disconnect and reconnect the USB cable, check your firewall settings to ensure printer communication is not blocked, Restart your computer"
I tried all of the above except checking my firewall settings because I'm not sure how to do that. I did a system restore a week or so ago, and before that I didn't have this problem, so I'm not sure what's changed.
Thank you in advance!
