<solved>scanner does not work [Solved]

[davidwillis]

Yes, it detects and finds the printer, but then gives an error when it tries to install the plugin. I think if I could just get the plugin installed it would work fine.

[JayM]

Can I please see your Quick System Info and the exact text of the error message you're getting (not a screenshot, the actual text in code tags.)

[gor9]

in addition to JayM advice,

your printer needs a plugin according to this page
https://developers.hp.com/hp-linux-imag ... lugin.html

Once you have re-run hplip as root, re-test scanner and if it does not work then run

Code: Select all

sudo hp-plugin

I do not own a hp anymore but in theory it should download the plugin (say) for the hplip v 3.21.4 from here
https://developers.hp.com/hp-linux-imag ... ng/plugins

HP plugin gives me this:

I think this is my problem.

Where are you getting this plugin and why do you need it?

[davidwillis]

When I try to scan something, it tells me I need the plugin. I have just been using the window that opens to try to install it, but then this last time I used the command sudo hp-plugin

Please provide sufficient information. What scanning app are you using? What specifically is "the plugin?"

[gor9]

to all

I think this is my problem.

I agree this is at least one problem. There may be more.
JayM writes in part...

this plugin and why do you need it?

my link in post 13 shows that scanner support is required as
HP LaserJet Pro MFP m225dn Required 3.14.10 1.Scanning support. 2.Faxing support.
The 3.14 but is the minimum plugin version.

the link suggests its extra firmware required for some services. OP should be able to print ok

[gor9]

an internet search shows one of the issues may be with the key server itself.

a possible solutions from the past is showing in this link
https://askubuntu.com/questions/1151526 ... successful

for the OP I suggest, assuming pathways are still correct

Code: Select all

sudo apt update
sudo apt-get install apparmor-utils
sudo aa-disable /usr/share/hplip/plugin.py
# next command must be non-root
hplip-plugin

if plugin downloads by bypassing the key server issue....give it a shot

####
below are my attempts to get the key

Code: Select all

gpg --keyserver pgp.mit.edu --recv-keys 0xA59047B9
gpg: keyserver receive failed: No data

and that key comes from
https://developers.hp.com/hp-linux-imag ... icate.html

[davidwillis]

Everything seemed to go fine until:

Code: Select all

$ sudo aa-disable /usr/share/hplip/plugin.py
