I have been trying to resolve the exact same problem with a wifi connected HP Officejet pro 8710 which up until 2 updates ago was printing perfectly. I suspected it was connected to the first update and hence waited until the next one to see if it went away.
I have completely deleted all printer set up files and drivers, cleared out the spooler and reinstalled the printer now 2 times and the problem persists. Both the HP and Microsoft troubleshooters say they can not find a problem. The job appears in the queue
, the printer starts up as if to print , the queue says that is printing and then it disappears without a print coming out. I have paused the queue and printed several jobs in a row which appear sequentially in the queue. When I remove the pause the printer
starts up and each one of the jobs shows as printing in turn until they have all gone from the queue but still nothing prints.
I am running Win 10, Vers: 1909, OS build 18363.836. The last major updates are as follows:
ON 3-4-20 2020-02 KB4537572 CUMULATIVE UPDATE TO .NET FRAMEWORK
ON 4-14-20 2020-04 KB4549951 CUMULATIVE UPDATE TO VERS 1909
ON 5-12-20 2020-05 KB4556799 CUMULATIVE UPDATE TO VERS 1909
ON 5-12-20 2020-05 KB4552931 CUMULATIVE UPDATE TO .NET FRAMEWORK
I have the same printer connected over the same wifi to another laptop running Win 10, 1909, build 18363.778 which can print just fine.
Updates on that machine are as follows:
ON 2-14-20 2020-02 KB4534132 CUMULATIVE UPDATE TO .NET FRAMEWORK
ON 3-14-20 2020-03 KB4551762 CUMULATIVE UPDATE TO VERS 1909
ON 4-27-20 2020-04 KB4549951 CUMULATIVE UPDATE TO VERS 1909
It appears as if the only major difference is in that PC2 is not updated by either of the 2020-05 updates that have been applied to PC1, which is odd because this problem started on PC1 after the application of 2020-04 update on 4-14-20.
Any response will be appreciated
Thanks in advance
