After patching up MAKEDEV as per:

http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=17162

...which really is a silly PR considering how easy the fix is, you can get
CUPS to talk to your printer once you add in pkgsrc/print/gimp-print extra
drivers.  BUT, to use the default/stock backends that come w/ CUPS, we need
to patch up the following.  It's IFDEF'd out (perhaps if configure probed
Solaris it would take care of this).  Anyway a quick if ${MACHINE} ==
"sparc" should fix this up.  Since or devices normally match the names of
those on the native commerical unix, other platforms should be able to use
the SGI, AIX, and HPUX stuff here too.  Shall I send-pr(1) with this?


one thing to note is that the device generaged by the MAKEDEV fix in the pr
gens /dev/bpp and this code looks for /dev/bpp[0-9]
