CentOS - Nov 2016 - Trouble setting up HP Officejet Pro 8600 printer on CentOS 7 + KDE

Hi,

I just installed a CentOS 7 + KDE desktop in my office's network. So
far, I'm quite happy with the results, though I have some trouble
getting the printer to work. All the other machines in my office
(server, desktops, workstation) are running Slackware64 14.1 or 14.2,
and they can all use the printer perfectly.

I installed hplip-gui and ran it. The printer is a network printer, it
has a static IP in the network and can also be addressed by its hostname.

  [kikinovak at alphamule:~] $ host hp-officejet
  hp-officejet.microlinux.lan has address 192.168.2.252

When I run hp-setup with the default options, the setup program "sees"
the printer, but informs me that there is a "communication problem". I
figure this is because the default seach method is mDNS/Bonjour. I tried
again with the SLP option, and this time the setup procedure went OK. Or
it seemed so, as the test page was blank.

Now what?

A few details about my system: SELinux, IPv6 and firewall are disabled.
CUPS is running OK. I checked on the HP website that this printer
requires HPLIP 3.11.10 or greater, which seems OK, since the HPLIP
version shipping with CentOS is 3.13.something.

Cheers,

Niki

Hi Niki
don't you need a hplip addon/plugin, which you can fetch from
http://hplipopensource.com/hplip-web/install/install/index.html

There, with the wizard, you get a file hplip-3.x.x.run
which you download and run using
bash hplip-3.x.x.run

This will install the addon/plugin.

Thanks, I got it to work indeed. Though there's a special utility called
hp-plugin to do that.

I did some more reading and experimenting, and I have a few general
questions about HPLIP on CentOS.

1. Generally, I have two options. Either go with the 3.13.x HPLIP
packages provided by RHEL/CentOS, or download the more recent (currently
3.16) HPLIP package on the HP site. Which way do you choose to go?

2. If I choose to go with the HP package, should I blacklist the
"official" packages provided by the distribution?

3. On Slackware systems, a normal user must be a member of the 'lp' and
'scanner' groups to be able to use a printer/scanner. How's that in
CentOS?

4. Is the proprietary HP plugin printer-specific or only specific to the
installed version of HPLIP?

5. Do I have to run hp-plugin *before* setting up my printer? Curiously
enough, I tried to setup my printer, but there was no automatic prompt
for the plugin download. Had to do it manually.

On a side note, I've always been favoring HP printers for my clients. On
Slackware systems (which I've been using until now) they're a breeze to
setup and work out of the box with HPLIP. Whenever I had some very
recent printers, I just built a package from the latest source, which
was trivial and also worked perfectly.
