The objects prtInterpreterFeedAddressability and
prtInterpreterXFeedAddressability should specify the MAX
addressability for the interpreter. This is fairly intuitive
for PDL's that carry image... 300, 600, 1200 etc. But, some
interpreters are completely text based with no image component.
I see three possible interpretations regarding what value to
use here.

1. Use -1 which means OTHER and places no restrictions on addressability

2. Use the finest text pitch supported by the device i.e. 15 pitch
would be 15 in units of 1/10000

3. Use the finest possible "actuation" (yes... I'm thinking along
the lines of impact printers and stepper motors here) in both
directions... with the notion that the PDL may be capable of
"overlaying" characters in very fine steps, regardless of their "pitch".

I vote for (1) above, for purely text based PDL's. However, I am
tripped up by the statement "places no restriction". I'm not sure
what that is trying to say.

I think at least one vendor, in the bake-off, used 10 for a language
called SimpleText. So I think they favored (2) above.

Any comment?
