What PPD are you using?

   grep Nickname /etc/cups/ppd/<your_XP-820_PPD>


See attached. I was originally using an different driver but when
that failed, I downloaded the latest escpr deb from Epson's support
site (v1.4.4) dated Oct. 31 I think.

Fine; this is the recommended PPD.

Looking at the "Set Default Options" from the Printers section at
http://localhost:631 there isn't an option to print to a CD. I do
not understand how CD/DVD could be selected as the output medium.

Brian.
There are two CD/DVD options. One is called CD/DVD-Standard. The other is called CD/DVD Premium Surface-Standard.
With the current driver, I seem to be able to able to set either one as the default Media Type. However there is no option for CD/DVD Media Size.
With the driver that I previously had installed, I had the same Media Size problem but CUPS wouldn't let me select a CD/DVD Media Type because there was no compatible media size. The latest driver from Epson removes the sanity check but still doesn't print to CD/DVD. When I try, it asks me to load a single sheet from the rear then ejects the CD tray and the tray that supports it, lowers the control panel etc.. 

Basically it doesn't work.

Looking at the ppd, I note that it contains the lines:
*MediaType CDDVD_HIGH/CD<2F>DVD-Standard: "<</HWResolution[360 360]>>setpagedevice" *MediaType CDDVDHIGH_HIGH/CD<2F>DVD Premium Surface-Standard: "<</HWResolution[360 360]>>setpagedevice"
but there are no *PageSize lines corresponding to CD/DVD media. I also don't see any *InputSlot for the CD tray but that could be because the CD/DVD tray sits on top of Cassette 1 (upper cassette).
There are also no *PageRegion or *ImageableArea lines for optical media. However there are several *UIConstraints lines that mention CD/DVD.
I can guess at what some of the lines are saying, but it's been decades since I looked at Postscript from a programming standpoint.
