@Dave_T2240 great to know you have come this far on your own!
Printer properties that are shown in client's printer dialog depends on the printer driver you are using on Connector. What driver is the PaperCut print queue associated to on the Connector?
Printer can define attributes either as standard attributes as per Windows PrintSchema or custom attributes. We try our best to map the standard attributes to Universal Print printer attributes on print users' devices.
We are working to publish more information on how to determine what print options will be supported for a given driver.
