Thanks to all that reply:

The answers I got were the following:
1. the parallel port in Ultra30 is /dev/ecpp0
2. boot -r
3. there is no sbus support in Ultra30 only PCI
The correct answer that I got from Sun tech support is
BugID 4082435
It is a bug in their new driver for /dev/ecpp0. Somehow it took them more
than 2 weeks to tell me that is a bug (after 7 calls to them!!!) Well,
hopefully I will get a patch soon to fix this. In the meantime the
printer is happily sitting idle in a corner...
Thanks to all...
