Thank you

Managed to test PR and unfortunate it breaks xsane (scanner) with

Failed to open device hpaio:/net/HP_Neverstop_Laser_MPF_120x?ip=192.168.1.201
Error during device I/O

but

  ~ $ hp-probe -bcups
HP Linux Imaging and Printing System (ver. 3.21.8)
Printer Discovery Utility ver. 4.1

hp:/net/HP_Neverstop_Laser_MFP_120x?ip=192.168.1.201  
HP_Neverstop_Laser_MFP_120x

Found 1 printer(s) on the 'cups' bus.

Please add
changelog="https://developers.hp.com/hp-linux-imaging-and-printing/release_notes"
and bump to version 3.21.10

I will test further issue with xsane this weekend..

[heindsight]

@biopsin thanks for testing. Not sure why xsane isn't working for you, it does work for me on my Deskjet 3630. One notable difference is that mine uses the LEDM backend and as far as I can tell the Neverstop MFP 120x models use ESCL, so I suppose it's possible there's been a regression for ESCL scanners.

I'll add the changelog and bump to 3.21.10 as requested.

@heindsight nope Im at loss; cant manage to resolve this, I've compaird hp-scan debug logs between 3.20.9 and 3.21.10, further tested hp-doctor -i outputs, there is just no significant diff between versions.
I will update this comment as I forgot to attach the logs..

[heindsight]

@biopsin That's rather strange. Could you rebuild with -UNDEBUG -DHPMUD_DEBUG -DESCL_DEBUG added to the CFLAGS set in the template?

Then run:

scanimage -T -d hpaio:/net/HP_Neverstop_Laser_MFP_120x?ip=192.168.1.201 --verbose

while tailing syslog? That might give some more insight into where things are going wrong.

[biopsin]

@heindsight sorry for the delay, I'll see how far I get today..

[ahesford]

@biopsin, have you had a chance to dig into the scanner issue?

[biopsin]

@ahesford go ahead and merge this, I will fiddle with it in the upcomming hollydays.
I'll rather open a issue if something is amiss with the template.

[Solved and Note]
After a hplip update, to make the scanner pickup the changes,run "$ hp-plugin" again and reinstall the scanner plugin. While the prosess it will complain and

warning: void distro is not found in AUTH_TYPES

error: Unable to recieve key from keyserver

but the plugin will eventually install successfull and xsane works again.

Anyway happy new year !!
