I am going to back down on my assertion. My understanding is that an application should query a printer for its attributes. I retested with the two applications earlier today but neither appeared to do this. For example. MediaType, ColorModel and cupsPrintQuality are not found in the "Device" section of LibreOffice. I imagine my previous testing procedure was defective. Regards, Brian.
