Windows 10: WINDOWS JULY 2022 KB5015807 CREATED DUPLICATE COPY OF PRINTER

Right after the July 11th install of Windows Update KB501587 I could not print. My laptop and printer connected USB to my laptop serves as the "Host Printer" for 2 other laptops on my network. When I started to investigate I see there is a 'Copy 1' of the same printer. I picked 'Copy 1' and I could print, but the other laptops would not. So I mapped the other 2 laptops on the network to print with 'Copy 1'. I have repeatedly set COPY 1 to the default. I do not have "let windows manage my printer' checked.After days of trying to trouble shoot this, I see that this is an issue with Windows upd

July 2022 CU KB5015807 breaks USB virtual port

Some of our workstations have an USB printer attached to a virtual USB. Windows shows the port as

Port Description Printer

USB002 Virtual printer port for USB {Printernname}

After KB5015807 installed, all of the machines with this CU installed had the printer to port connection broken, leaving the workstation unable to print. Now the Description shows as "UnknownPrinter" an the port is no longer selected for the printer.

Simply selecting (put the checkmark back) on that line with UnknownPrinter has things working again.

KB5015807 breaks something in this regards. There is a short posting on Reddit of others that have had the same issue.

 

automatically adds duplicate printer copy

Hello,

I have encountered an issue on Windows 10.

I have an older printer which works fine on initial setup. Prints and is set to default

• MY_BEST_Printer

The issue comes in when I unplug the USB cable and after some time plug, it back in it adds a new duplicate copy of the same printer.

• MY_BEST_Printer (Copy 1)

This new duplicated printer is not set to default, so obviously, it does not send print file to the same queue pool and it does not get printed.

And if I keep plugging and unplugging it keeps adding new duplicates.

• MY_BEST_Printer Default

• MY_BEST_Printer (Copy 1)

• MY_BEST_Printer (Copy 2)

Is there a way to stop Windows 10 from adding the same printer as a duplicate if it sees that it is the same printer?
