Have you read the OS/8 handbook? It tells you pretty much

I've never used the OS/8 image that comes with simh so I’m only
guessing, but it sounds like it doesn't have a device driver for the
printer (it's called a device "handler" in OS/8 lingo) installed.
You'll need to install one. It tells you how to do that in the
handbook.
Correct.
Adding a device in simh is equivalent to putting the card in the
backplane. That does not mean the OS automatically knows about it. You
also need to configure the OS side of things.
Seriously - for the OP - you need to start by actually learning the
OS, and not just fool around and expect things to just work, or other
people tell you the obvious things.
The OS/8 handbook is really required reading before you ask any
questions where OS/8 is involved.

Yes Johnny I have looked at a few OSes from DEC days and the pdps 8 and
11 are interesting I think. So I will spend some time with OS/8 and I
think tts8 and maybe rx or rsx is pdp8. Anyway RSTS is a descendant of
the PDP8 OSes. OS8 anyway.
A little confusing text, but from what I *think* you say:
RSTS could possibly be said to be a descendant from TSS-8.
RT-11 have a very clear resemblance to OS/8.
RSX don't really have anything close on the PDP-8 side. The closest
would be RTS-8, but it's not very close. RSX comes from the PDP-15
originally.
But no matter what OS one wants to play with, understanding the OS is
important. Just fiddling with the simh side is not going to cut it.
