RFR: 8375221: Update code to get PrinterResolution from CUPS/IPP print service [v3]

[Phil Race]

> Previous to this fix, no resolution was being found via CUPS/IPP and when the test case for printer resolution was falling back to the made up 300dpi setting. With this fix it finds the 600dpi from CUPS/IPP.
