2000 Printer Port

I'm working on a VAXStation 2000 running Ultrix 4.0 and trying to get
a non-DEC laser printer hooked up to the printer port.
Here's what I have found from the hardware manual and messing around with
the setup:
printer port is a fixed 4800 baud
with KERMIT, I discovered the port is /dev/tty03 and that
I can talk to the printer's interpreted PostScript mode
in what appears to be 8-bit no-stop-bit communcation
I ran LPRSETUP and the command updated /etc/printcap
However, when I try to ship files in with LPR, the printer's status panel
flashes between PROCESSING and IDLE, then stops and nothing prints for
PostScript; in HP laser emulation, I get a few 1's and 2's scattered
over a single page that does print. LPQ shows the queue empty when
either of these completes.
What are the exact parameters of the 2000's printer port? Especially:
Baud (4800 only, it appears)
Parity (none?)
Stop bits (1?)
Flow control (XON/XOFF? DTR?)
And, any suggestions on why I'm not getting even partly-readable output?
For the curious, the printer is a NEC LC-890 and I'm using a 9-pin
straight-through cable from 2000 to a 9-to-25-pin adapter to the printer's
DB-25 serial port.
Mail or posting back on this would be appreciated. Thanks much!
