That's telnet printing onto the printer raw port; onto the PDL or PCL 
or TCP port 9100 port.  A little unusual, but the Brother is clearly 
dealing.  I'd tend to expect TCP 23, or LPR into LPD on TCP 515, but 
this works.

Port Scan has completed…

The whole of OpenVMS printing is archaic.

The addition of IPP support with VSI IP MultiNet support will 
definitely be beneficial for printing.

MultiNet also has support for mDNS and which can be used to detect and 
evaluate printers on the local network.  Where some future printer 
configuration and control tool can show you the local printers, and can 
offer to preconfigure the selected printer.

CUPS support has been requested once or twice before, as well.  That'd 
effectively replace most of the existing printing subsystem, including 
DECprint Supervisor (DCPS).
