Oi,

I have talked with Mike Sweet on the phone, for him all days in March
are good. Also East coast is OK with him. He would like very much to come.

And Mike and me have aggreed on one proposal for changing the printing
architecture under Linux and Unix:

The standard format for print job transfer should be moved from
PostScript to PDF, to have a more powerful and reliable format and a
format which is better supported by free software, as the free
GhostScript versions (GNU/GPL/ESP) are already old (one year older than
AFPL) and not maintained as well as AFPL, but XPDF is well-maintained
and XPDF people are more cooperative with the CUPS developers. One
should add IJS, CUPS,and OpenPrinting vector interfaces to XPDF to talk
with drivers and modularize the remaining GhostScript compile-in drivers
into one legacy-driver IJS plug-in (GhostScript-aware developers needed
for that). A side effect of separating all drivers from GhostScript is
also that by adding IJS, CUPS, and OpenPrinting vector interfaces to
Cairo one could print on embedded systems without memory-consuming
high-level transfer formats (PDF, PostScript).

What do you think about this step?
