All three printers display fine in macos 10.7.5.  I will try to chase this backwards to see if I can tell what version of macos this might have been the start of troubles.

There are plenty of one-off printers.  The XML isn't visible outside of Gutenprint; I'd be pretty
surprised if that's the problem.  These are both complex wide format printers.  I suspect it's more
likely that we're running into some limit, perhaps total PPD size, perhaps number of options or
values (in particular, number of paper sizes; IIRC that was a problem in the past).

If paper sizes is the problem, there are various ways to test it.  One way might be to check the
Epson Stylus Photo R1800 vs. the Stylus Photo R800; the R1800 is the same as the R800 except for the
width (13" carriage vs. 8.5").
