Windows 10: Making a LaserJet 4100 print darker?

I have a monochrome PNG I need to print onto self adhesive plastic film. It has to print DARK black so light won't shine through the printed area.

I used to print these on a Color LaserJet 2500 but it broke so the 4100DTN is what I'm stuck with. The default Windows 10 driver doesn't appear to have any options for print density aside from choosing 300 or 600 DPI (despite the printer being 1200 DPI) and RET on or off.

I set on the printer itself to ProRes 1200 and toner density to the maximum of 5. All the on-printer settings can be overridden by the Windows driver or by application software. I can make it print *lighter* in some cases such as having Adobe Reader tell the printer to do so.

Is there a graphics program that's able to override Windows' driver settings and directly command the printer to use its highest quality/density settings that aren't available in the driver?

What'd really be nice is a 3rd party driver that has all the settings that have been taken out of the cut down driver with Windows.

My HP printer has HP driver options for print density and print all text in black. You could try those?

The 4100 is an older printer. What I'm printing isn't text so that setting doesn't apply. The drivers Microsoft provides for printers often are "feature reduced", meaning the full capability of the printer is hobbled by leaving out support for things like the maximum resolution and print density options.

In the case of the LaserJet 4100, some apps like Adobe Reader can override or bypass the hobbled driver and make the printer print *lighter*. I'm wanting to go the other way to make it print *darker* than the default middle of the road setting, like was possible with the HP driver with Windows versions before XP.
