Brother MFC-L2750DW doesn't print, sometimes

[ChrisDx]

Here's something weird. We have the above referenced printer in our household. It prints fine with 2 MacBooks, and 1 WinOS laptop through WiFi. However, it doesn't always work from my ethernet-, or WiFi-, connected desktop iMac. The Print Queue dialogue says "Printing – Connected to printer", but nothing happens for quite a while. Then the job either prints, or not, and the job disappears from the Print Queue.

The firmware is up-to-date on the printer. I am using High Sierra [10.13.6] on the iMac and older versions on the 2 MacBooks.

Any help or insight is much appreciated.

Here's an update. After a couple of hours, the job disappeared from The Print Queue dialogue box. I walked to the store, bought some bananas, tried printing again, and it worked. What conclusions should I draw?

Do you have both WiFi and Ethernet connected at the same time on the iMac? Don’t, that causes connection issues between Brother printers and Macs. Disable one or the other then restart.

I've had both on, as well as one of each on. Sometimes it works, or not, with or without restart.

I'd DELETE the existing Brother print driver (in the printers/scanners pref pane), and re-install and re-do your settings.

No promises.
It might help.
