MFC-2750DW does not print, sometimes on iMac

[ChrisHGSA]

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. 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?
