Airprint Does Not Work with MacOS 10.15.6

[billmclade]

Hi There

This is my setup:

• MFP M277dw
• 2019 MacBook Pro, running 10.15.6
• 2019 MacBook Air running 10.15.6
• 2017 MacBook Air running 10.15.6
• 2012 MacBook Air running 10.15.6
• 2011 iMac running 10.13.6
• an iPhone X running 13.5.1
• a ubiquiti Unifi network
• All devices are connected to the same wireless network SSID

This is the current situation:

• The 2019 and the 2017  DO NOT print using Airprint
• both the 2011 iMac and the 2012 Air DOES print over Airprint
• The iPhone DOES print over Airprint 

I can see a number of posts relating this topic, and have already done the basic checks and processes -ie:

• The fact that some work confirms the notion that my network supports Bonjour.
• The HP Smart App on the 2019 Pro allows me to see configuration and supply levels. It also allows me to trigger the scan. This shows there is a connection between the laptop and the printer
• I have followed instructions on unplugging printers, and resetting the printer setting in MacOS. both of these have proven fruitless

I cant see any of the previous posts having a solved outcome. Hoping someone can help.

Do you get an error when printing from the failing devices?

Your post is titled "AirPrint does not work in 10.15.6" but in your description you say your 2012 MacBook Air running 10.15.6 does print over AirPrint.  So, it's most likely not an OS specific issue.

The most common fix for issues like this is to delete the existing print queue and re-add it.

If that does not work try a Reset Print System.  You mention something about resetting settings but was unsure if you performed the Reset Print System.  Then add the printer again.

If you are currently connecting with "Secure AirPrint" try deleting the existing queue and setup using just "AirPrint".
