My printers installation

SUMMARY
I learned that my printer can be installed as driverless. I deleted the
instance that uses a driver and created a driverless instance. Although I know
that this printer supports duplex printing none of KDE apps I have tried will
allow me to choose duplex.

STEPS TO REPRODUCE
1. Install printer with the driverless option
2. Choose a KDE app and an appropriatte file
3. Open the app's print option
4. Expand the the printers options and look for double sided printing
5. Try to click on one of the double sided options

OBSERVED RESULT
The double sided options are grey and cannot be selected.

EXPECTED RESULT
I should be able to choose one of the double sided options.

ADDITIONAL INFORMATION
If I use a non-kde app such as Libre writer the duplex option is available.
The printer using the driverless installation is actually able to print double
sided.

"lp -d HP_LaserJet_MFP_M232-M237 -o sides=two-sided-long-edge my-file" confirms
that double sided printing works.

For further testing added the driver option back on an extra instance of the
printer. I confirmed that the duplex option is available when using the driver
instance.
