Printing to networked HP printer hangs from Macs, all Windows PCs print fine
Since this appears to be a new problem that started around the time of the most recent OS update a week or so ago, I am starting a new discussion. I have already read and tried all solutions documented here: Printing to a networked HP printer hangs. I have also read and tried all generic solutions about resetting the printing system, and deleting the folder that contains the printer drivers. All to no avail.
Here is the situation:
This is a home network with an OfficeJet 8600 Plus that has worked perfectly with three PCs, a MacBook and an iMac for a long time. It continues to work perfectly with both PCs. Both Macs hang, saying the job is 1% complete for large print jobs, and the small print jobs simply disappear from the queue as though they were complete, but do not print. I have used AirPrint only, until I started to try to debug all of this two days ago. Then I installed the latest HP print drivers on the iMac only. Note that there has been no update to the printing part of the drivers since 2015. Only the scanning part of the drivers has been updated a couple of months ago.
At the end of the installation of the HP drivers, it suggests printing a test page and scanning a test document. Both work perfectly. However, nothing prints from any application on the Mac. All applications can see the printer, which is reported as Idle before printing starts. Scanning works normally.
I have made no change to the Netgear router I use in the last 12 months. I have not installed anything new on either Mac, other than the OS updates and whatever application updates may be happening in the background without my intervention.
Setting up the printer queue to print to the IP address of the printer changes nothing. The printer has a fixed IP address. Resetting the printer completely and installing it from scratch changes nothing. Multiple reboots of everything change nothing.
Since the problem affects both Macs, I suspect something happened in the most recent OS update. I have a dangerous level of knowledge after 28 years in the IT industry, including 14 with HP.
All ideas welcome.
