Hello Hplip maintainers,

i recently bought an HP deskjet 2050 printer/scanner/copier
and found that it copies well and prints well, but doesnt scan.

It was mentioned on HP's hplip pages that this machine is "fully"
supported for Linux,
so i had a conversation with their helpdesk
(available on https://answers.launchpad.net/hplip/+question/173135)
from which i learned that the machine doesn't scan with Debian because
the drivers have not been installed.

I looked a bit further, and found Debian bug #451502,
which mentions that (these) HP drivers are non-inspectable and
non-distributable.

While trying to find out what was wrong,
i used program 'hp-check', provided by hplip package.
When running 'hp-check -r -t', it reports as summary : "no errors or
warnings",
despite fact that it has found (reported in section 'plugin')
that values of persistent variables are
installed=0
eula=0
which apparently means that the driver plugin is not installed.

Without this plugin, this machine can not scan,
and therefore i think that 'hp-check -r -t' should not have reported
that there were no errors or warnings,
but should rather have warned that the driver is absent.

This would have saved me some time trying to figure out what was wrong.

I also found that with 'hp-check -t' i get some errors that are not
reported as compile-time only, while they do not show up with 'hp-check
-r -t'.

Thanks for providing hplip ;
this deskjet 2050 prints well, and works right out of the box.
(and for scanning i'll buy a canon lide 110).

Can you please upgrade the HPLIP driver to 3.12.2. Please download the latest hplip from http://hplipopensource.com/hplip-web/install/install/index.html and install it.

Delete the print queues by running in terminal "system-config-printer" and add the queue by running in terminal "hp-setup". Post the output of "hp-check".

You can run "xsane" or "hp-scan" for scanning. If you find any issue in scanning, post the output of "hp-scan -g"
