First of all thanks for your reply.

You're right Michael. I posted a version of the PPD with the stanza

*UIConstraints: *PageRegion [all but envelope/none page regions] *MediaType
Envelope 
*UIConstraints: *MediaType Envelope *PageRegion [all but envelope/none page
regions]

commented out (lines 1361 to 1383 of my PPD). My bad.

That explains why you were able to select the MediaType Envelope: commenting
out this stanza makes things work.

The answer remains: if there is no *UIConstraints preventing the selection of
"DL Env." PageRegion along with the "Envelope" MediaType, why does enabling
this stanza (as in the original PPD) change things?

Oddly enough, the "4x6" PageRegion also has a stanza which allows only the
"Card" and "none" MediaTypes but in this case "CardStock" appears in the list
available for selection without the need to disable the stanza.

I'm also wondering whether it makes sense to have constraints for PageRegions
when the same constraints exist for the PageSizes.

Regarding ~/.cups/lpoptions, getting rid of it unfortunately didn't change
things when the above mentioned stanza is not commented out.
