LASER JET PRO M278 No Longer Printing since Catalina update

[gfroiz]

Air print will send the job to printer- 

Printer initiates "clicks" and then closes.

USB is not recognized.

I have tried uninstalling and re-installing.

Checked router, checked USB,

Checked with APPLE

Checked with Vendor who I purchased from.

HELP.

@gfroiz, Welcome to the HP Support Community!

Have you tried using an alternate USB cable?

Let us try these steps to resolve this issue:

Update the printer firmware

Click here to know different methods of updating printer firmware.

Also, check for any software updates on MAC

Click the Apple icon > About This Mac > Software Update and install any available update.

Make sure the cable is directly connected between the MAC and the printer.

The use of a USB hub is not recommended. Also, make sure the cable is connected to a USB 2.0 port on your MAC.

Do you have an Anti-virus/firewall installed on the MAC?

• Check if the printer is getting recognized by your MAC:

1. From the Apple menu, choose About This Mac.
2. Click System Report.
3. Under the Hardware heading on the left side of the System Information window, click USB.

USB 3 devices appear under USB 3.0 Bus, and USB 2 devices appear under USB 2.0 Bus. The printer should be under the USB 2.0 Bus.

Refer to this document to know how to install the printer using a USB cable.

Hope this helps! Keep me posted.
