daveyPlease, don't type or verbalise what you see, copy/paste into your post.
There is no way that
lptstat will not work if CUPS is running, unless you do just what I did. My brain knows what it should be so I don't
see there is a mistake. (I was so taken back that I actually stopped and looked at what you had typed, I had already assumed what the statement was flying over the text)
Anyway copy from my command line below and try again.
[gert@localhost ~]$ lpstat -t
This line is important, it will tell
as and myself a lot if it is working.
If CUPS lets us down you/we have a problem

You will see that I have your Laserjet 6MP installed in "some form" but this is not the only way it can be done.

[gert@localhost ~]$ lpstat -t
Edit:addedI need the answer to the
lpstat -t so that I can provide the copy and paste instructions that in a few steps will display your complete setup (if you have it right) if not then
as will sort it out
