[Given up] Adding a network printer

[pdc_2]

the posts in Mint are not numbered;

but in post #3 if one counts from the beginning I said

so HP say this printer needs a plug-in;

it is all back there

[turboscrew]

Installed it, but it didn't help.
I thought it was installed, but hp-check revealed it wasn't, so I installed it.

BTW, The HP device manager says:

HPLIP cannot detect printers in your network.
This may be due to existing firewall settings blocking the required ports. When you are in a trusted network environment, you may open the ports for network services like mdns and slp in the firewall. For detailed steps follow the link. http://hplipopensource.com/node/375

When I try to search printers.
Which firewall is Mint (17.7) use by default, and is it ON by default?

Code: Select all

# ufw status verbose
Status: inactive

I installed ufw, since there seemed to be no firewall manipulation programs installed by default. At least "man -k firewall" didn't find any.

And is reboot needed after installing hplip?
"netstat -lntu" shows that the ports 5353 and 427 are not listened.
Port 5353 is there in the listing, but 427 is not.

gufw is the GUI front end for ufw, install from software manager.

[turboscrew]

Installed that too.

Also, should there be open UDP ports? Especially, if the firewall is insctive?

Code: Select all

$ nmap -T4 -A localhost

What the ...
The hplip just started working by itself?
I did nothing, but it suddenly started to find the printer...
(well, I did some port scanning, but that shouldn't have any effects.)

Now what's left is figuring out if the name can be used instead of IP.

Hmm, if there are no printers, the HP device manager doesn't seem to find anything (if started from icon).
But run from command line 'hp-setup -i' seems to work. After that the HP device manager (even if started from the icon) finds that.
It can't show the colour levels, though.

good work; working away on your own computer pays dividends;

I was curious where you got

Code: Select all

hp-setup -i

from; (I see now it means interactive);

if one does

Code: Select all

man hp-setup

in the terminal; and full-page it to read, there are a host of options to explore;

let us know when you think the printer is behaving as it should; and so let us know when you think the problem is resolved; (after installing the plug-in, a reboot may be needed to get all the stars aligned);

[turboscrew]

Status update:

Hplip works partly. It detects the printer, and the 'print settings' and 'printer control' seems to work.
What doesn't work is 'status' and 'supplies'.
On both pages it says "information not available for this device".
The 3.16.x on my Debian machine everything works, but it's from the backports-repo.

The printer still uses static IP and was added by IP.

hp-setup --help
hp-makeuri --help
hp-probe --help
and especially:
hp-toolbox --help (gives a nice list of hp-commands)

The boot wasn't needed, but something else seemed to take time.

[turboscrew]

In this adventure, also nmap became a friend.
(and also nmapsi4 - gui for nmap)

[turboscrew]

I guess Mint people should get a bit worried, if Debian has newer hplip than Mint.

[turboscrew]

Status update:

It may be that adding this printer by name is not possible. I found another URI-form, but it didn't work with this printer.

Code: Select all

hp:/net/Color_LaserJet_MFP_M277dw?zc=NPIB88B68

Also tried

Code: Select all

hp:/net/Color_LaserJet_MFP_M277dw?serial=NPIB88B68

but it didn't work either.

Also hplip-3.17.11 doesn't seem to work properly. Using the manual setup ("hp-setup -i" and using the IP) got the printer installed, and it prints, but the GUI can't get any info from the printer. The embedded web server works fine, though.

[turboscrew]

It looks like it's time to give up, and settle for static IP...
