I am attempting to install a bluetooth printer (Zebra RW-420) on a Windows 7 Professional 32-bit machine. This works fine the first time, but when I uninstall & unpair it and then re-pair it, the device gets set up on a new virtual com serial port. At this point, I can not install the printer itself, as the print dialog does not show the com port in the list. I have tried and can NOT reproduce this on two other machines, one running Windows 7 64-bit and one running windows 8.1 64bit. Could this be a bug in Windows 7 Professional 32-bit?
My steps:
1) Click "Add a device"
2) Click "Printer", click "Next".
3) Enter "0000" pin. Click "Next".
4) Bubble from Tray area says "Standard Serial over Bluetooth link (COM4)"
5) Add Printer dialog OR Run "cmd", enter "cscript C:\Windows\System32\Printing_Admin_Scripts\en-US\prnmngr.vbs -a -p "ZDesigner RW 420" -m "ZDesigner RW 420" -r COM4:"
6) Added printer "ZDesigner RW 420"
7) Print a test page. (Ensures that the next port will show up on a new port.)
7) Remove printer "ZDesigner RW 420"
8) Remove bluetooth device.
9) Repeat steps 1 through 3.
10) Bubble from Tray area says "Standard Serial over Bluetooth link (COM8)"
11) Click "Add Printer" (can't get past port selection screen, as port doesn't show up in list.) OR Run "cmd", enter "cscript C:\Windows\System32\Printing_Admin_Scripts\en-US\prnmngr.vbs -a -p "ZDesigner RW 420" -m "ZDesigner RW 420" -r COM8:"
12) "Unable to add printer ZDesigner RW 420 Error 0x80041001 Generic failure
