I am having issues with Windoze 10 and a HP M404dn printer.

I tried 3 different drivers, with mixed results.

The first two drivers are Win 10 x64 PCL. The driver install properly, work properly in Windows. Comet will do a Print Screen from the menu bar, but the printer is inaccessible to Comet programs.

I doubled & tripled check the printer name in PTRDLG. to no avail.

It is configured as a local printer connected to an IP port.

The third driver I tried, is the "generic" PostScript driver. This one Comet can see and print to, but paper tray selection does not work. This printer is used to print on Letterhead Paper from two different trays. This worked for years.

Why wouldn't Comet be able to access this properly configured Windoze printer using PCL drivers?

Is there a way to get Windows version from Comet ? So I can create an exception for Windows 10 to use different Trays #. Its 1,3,2 for PCL and 256,260,261 for PostScript.

The printer used to be a M402, it is now a M404. We still name it M402 for compatibility with Comet configuration.

Printer = LST,W,N,,HP_M402n,,; ! HP LaserJet Pro M402n PCL 6 Acct Can + USA

Windows 10 Pro version is always latest because it is auto-update.
