The problem is not the need for an inverter but the right cab kit so it
all come out to the right connector.

I may actually have a printer to go with it. A BIG thing, not

We used to use an LP25 on our DMF32 (Unibus ancestor of the DMB32). It
was a Dataproduct printer with a DEC badge. I do recall seeing a simple
circuit somewhere involving an inverter or two to attach a Centronics
printer to an LPV11. It shouldn't be a complicated matter to examine
which signals on the DP port are low-true and which ones are low-true
on a "Centronics" port and deduce which handshaking lines need inverted.
