printing problems after Mojave update. offending command: imagemask. Help!

[JS1030]

Error: limitcheck.  Offending Command: imagemask.  Just updated to Mojave.  Also, recently tried to enable network connection, which seems to have worked up to a point, but still unable to print from any other device.  Happy to have it as it was, printing from my MacMini.

I have gone through your Post and would like to help

We will test the wireless network connection first to ensure the 

a. Go to Applications, then Utilities, and open Terminal. b. Type ping followed by the router IP address. c. If the window displays round-trip times, the network is working.

Next ensure that the router or printer connects to the same network that the computer connects to. a. Print a configuration page. b. Compare the service set identifier (SSID) on the configuration report to the SSID in the printer configuration for the computer. c. If the numbers are not the same, the devices are not connecting to the same network. 

If they are not connected to the same Network,  Reset the Printer to Factory Defaults

For 2-line control panels: On the printer control panel, press the wrench button and for Touchscreen control panels: From the Home screen on the printer control panel, swipe until the Setup menu displays. Touch the Setup icon to open the menu.

2. Open the following menus: ● Service ● Restore Defaults

3. Touch or press the OK button. The printer automatically restarts.

Then run the wireless setup wizard to connect the printer

Try printing and let me know how it goes

Thank you and have a great weekend 😊
