HP DeskJet 2778 All-in-One Ink Advantage Wireless Colour Printer not working

[mxmatrix]

Actually printing is 'sort of' going well. Except some margin problem.
The main problem right now is Scanning feature is just not working.
To scan I have to do that through any android device only.

I've already told you my use case in this thread. I have multi users in the home on different devices. My home network has a firewall. Wireless works for me.

Sorry, I asked something slightly different :

(1) Someone mentioned that a driver is anyway needed even if connect by wireless. Is it so ? If not then will it help me in my 'case of non-functioning printer' especially if I do not have a multi-user (and multi-device) environment.

(2) I am concerned about the privacy aspect in wireless printing / scanning. I am afraid in wireless system there is possibility of my documents being routed through servers on the internet. Is it so ? Which in any case is unacceptable.

As I am not able to find a solution to the problem, I started scanning using an android app.
I dedicated one old mobile for this purpose, till I can find a solution to use my printer / scanner directly from my linux computer. Preferably using USB cable.
When I started using that app using Direct ... wireless connection, I felt 'may be' it is not that insecure compared to printing over wifi.
Can we do a similar thing on Linux ?
I know many of you have advised some packages but I am either not able to locate them on the repo or they are not working.
Like HP's website advises to use HPLIP 3.20.x but it is not working in my case.

"Just not working" doesn't tell us very much. Is your scanner detected in SimpleScan but just won't scan, or is it not even being detected, or what? And are you currently connecting to the printer via wifi or USB? People need details about the problem if they're going to be able to try to help you.

BTW HPLIP 3.20.9 is available in the test repo in MX Package Installer. Also I think you need to run

Code: Select all

hp-setup

in a terminal, enter the root password if requested, then select either USB for a directly-connected printer or JetDirect for a networked printer.

Well, I can understand that this post is running since a long time and though most of the information that you asked for are already mentioned in the thread. I also understand that it will be difficult for any one to go through all the posts so what ever information you need I can sum up again over here.

Basically I am using HPLIP 3.20.11
I have tried

Code: Select all

hp-doctor
hp-setup
hp-plugin
sudo hp-plugin

They all give some error or the other. Which have been posted here earlier. Tried installing N number of files from repo to solve any kind of dependency problem but till now none worked.
Like earlier sudo hp-plugin used to give some 'proper error' but now it does not even says anything just mentions 'plugin could not be installed'.
In HP-toolbox I have mark my printer as another printer as it does not displays 2700 series in the list of printers and that some how helps me take prints. Though HP's website mentions that HPLIP 3.20.11 'fully' supports 2700 series but still hp-doctor says that 2700 is an unrecognised printer.
Regarding scanning, Simple scan says No printer was found.
I use an android app to scan from that printer from a mobile and then transfer the files to my computer.

(1) Someone mentioned ...

Me

Imho that (wifi) only provides communication / connection bw. the pc and the printer. Instead of using a wire...

So, it's best to connect HP someway and ask to be sure before purchasing.. (also about the "series" subject ... )

Though this is just a "guess".

And that was what I was trying to tell before you purchase:

But imho what's more important for both is:

8 ("Yes") A downloadable driver plug-in is required for printing support. ... ("No" or "None") A driver plug-in is not required nor available. Driver plug-ins are released under a proprietary (non-open) license and are not part of the HPLIP tarball release. For more information, please refer to this KB article

P.S. The words "required" are added by me :)

Say, your old one, 2135 is "No" (requiring no proprietary drivers) ... working ootb.

So if their proprietary drivers are not available for this printer (or might not work in some cases) then why at all do they mention that printer's name in the list, especially when they also mention the term FULLY supported for it ?

Anyway so what do I need to do with this printer ?
(1) forever depend on android to use it's scanner
(2) throw it our of my window ?

This link which you mentioned does not even has the name of that printer there.

I haven't read every post in this thread, but have you tried:
MX Package Installer
MX Test Repo
delete:
hplip 3.20.9
hplip-data 3.20.9
hplip-gui 3.20.9
Then open synaptic and install:
hplip 3.19.6
may have to install hplip-data first
then
hplip 3.19.6
hplip-gui 3.19.6

The 3.19 series worked for me the 3.20 would not find my printer as a scanner.
