Thanks for the response.

I did have the firewalls on both machines properly set,
with port 9100 (TCP and UDP) added.
Now I've disabled the firewall on both machines.
The printer was set as sharing on both machines.

I'm wondering if I have caused some confusion
by install hplip on machine A,
and running hp-setup there?

I'm not at all clear of the relation (if any) between hplip and CUPS?

I like hplip because it recongized my Laserjet 5L,
and claims it can clean the print-head.
(I'm slightly sceptical of this claim ...)

But I'm thinking of removing CUPS and hplip, and starting from scratch.
