Help needed connecting laserjet to Sun

[Sangho Yoon]

I'm trying to connect a Hewlett Packard LaserJet II to a Sun 3/110.  Can
anyone tell me what I have to do to get the two to talk to each other?
Currently, all the printer does is print blank pages whenever I send
anything to the printer queue.  

The LaserJet is connected by a serial cable to ttyb on the Sun 3.  I've
checked the baud rate, made sure getty wasn't running on the port, and set
up a printcap entry.

Help!
