How to check the selected printer is Windows only Printer?

[RAMESHBABU]

Hi all

Can anybody please guide me to check the selected printer is windows
only printer ?

I am providing both DOS and Windows Printing feature in my application.
I have a problem in implementing both the features. When the user has
selected the DOS printer or the default printer is DOS printer and the
Windows only printer is switched on and currently available for printing,
the windows only printer is printing junk due to the presence of ESC
sequence character in DOS output.

So before I release the print command, I want check that the selected
printer is Windows only printer or not and act accordingly.

How to check this?

Thanks
