Peter -

The printer port on a VAXstation 2000 should automatically be configured 
as /dev/tty03.  The results of...

% file /dev/tty03		(should be)
/dev/tty03:     character special (45/3) VS_SLU #0 terminal #3 

Check "man 4 ss" for a few more details.

BTW - the cable Digital provides to connect this to a standard printer 
is the "BCC05".  It looks just like the "BCC08", but has a critical 
difference.  The BCC08 is designed to connect consoles to microVAXen.  
When the terminal is shut off, or the break key is hit, the microVAX 
will interpret the break as a command to go into console mode (">>>").

In addition, when a VAXstation 2000 is booting, it checks this 
connection to see if it has a console attached.  If one is, the console 
moves over.

If you attach a printer with this cable, you've got a few problems.  
When you turn off the printer, your system will go "console."  When you 
boot, the console will move to the printer.  Not amusing, eh?  The BCC05 
solves that.  The BCC08 says "console" on the end connector, while the 
BCC05 says "PR".

I don't know what the wiring difference between the two is, sorry.
