Determine if a printer is "Professional" or OZ/Jedi
I am registering buttons for access to our services. Everything works just fine.
However I came across a caveat regarding the format required for the icons to be used.
It said "Professional" devices need PNG files; OZ / JEDI devices need GIF files.
So, how can I simply and reliably determine which type of device it is, so I sent the right type of icon image?
