LaserJet Printing

About 50% of the documents sent via wifi to my Color LaserJet Pro MFP M281cdw show to complete in the queue, but never print. To be clear, it's not that they are stuck in the queue, they just disappear without printing. I can't see any pattern to when a document will print and when it won't. On our laptop (Mac OSX running High-Sierra), the document shows in the print queue (searching for printer, sending document, print complete, empty queue). This same thing occurs just about as often when printing from a mobile device (No error message, but also no print). It has happened often that a certain document will do the disappearing thing, but I can immediately print another document from the same device without changing any settings.  I have tried several times to .pdf the problematic documents, but the .pdf behaves exactly the same (shows to print in the queue, but never prints).  The behavior doesn't seem to be specific to any application - MS Word, Pages, emails, Safari, Chrome, etc.

I have restarted everything several times (Modem, Router, Laptop, iPhone, Printer). I verified that the printer firmware is up to date. I have deleted and reinstalled the print driver on the laptop several times. I verified that all devices are recognized on the network and that there are no IP conflicts. Despite all of this, the problem has persisted for several months.

Though I can't see a clear pattern in the type of document that will or will not print, there are some that will never print. For instance, if I open a new document in Pages using the certificate template, it will not print.  The problem does seem to happen more often with graphics heavy documents, but not every document with large graphics produce the problem. And not every document that disappears has graphics in it. Documents that won't print seem to print easily and quickly on our older Brother printer from the same devices.

Anyone had this happen and found something that will help? Any help would be appreciated.
