[cups] Can't print to a local HP LaserJet

[Ken Wright]

I got a new LaserJet M15a recently and installed it on my home server. 
I can see it and install it with the CUPS web interface, but it's not
printing.  I know the printer works; I tested it with my laptop.  If
anyone can shed a little light on my problem, I'd be grateful.

I'll be happy to provide further information, outputs of commands and
diagnostics, anything needed to help.  Thanks in advance!
