Can a malware or bug get in your PC through a connected printer ?

[Gidouen]

Trying to print an Excel page on my printer (not connected by wireless but connected with a cable), I had a black screen and since then, I can't use the printer (message of error appearing every time I switch it ON, and yellow light on, blinking . Since then, I can't open any EXCEL file.

@Gidouen, Welcome to the HP Support Community!

If you are not able to open excel sheets, it could be an application issue. Try repairing or reinstalling Microsoft office.

Refer to this document.

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Re-insert the ink cartridges.

Try making a standalone copy and check if that works. By this, we can conclude if this is a hardware or a driver issue.

Try printing PDF or emails and check if that works.

Hope this helps! Keep me posted.
