I am doing a fresh install on a new Windows computer (using a clean 1903 install), and cannot use my existing printers. The EasyWirelessSetup 3.7 (and 3.6) from the hp site no longer do anything at all when they run, they just report finished and don't actually install any drivers or detect any printers. I have re-re-reinstalled windows fresh (with completely reformated partitions), and the same thing happens.
The best I have been able to do is make a fake PCL6 printer using Microsoft's default drivers, and point it at the ip address of each, but this is VERY unsatisfactory as I cannot adjust any print features or even select a paper source.
I have tried running the EWS as administrator, as well as in compatability mode for win8, but it still instantly completes without doing anything.
