HP All-in-One Printer No Longer Scanning

This may be useful in determining how CUPS is currently configured...

Code:

lpstat -t

Code:

egrep -i "name|model|filter" /etc/cups/ppd/*

I think the next output will blow the character limit so will start a new reply.

Sorry I have conflated the quotes somehow but it should all be clear. Here is the result from your last instruction:-

Sorry, I had to shorten this but you will get the gist and if you tell me what to grep I can follow your instruction but the output ran to 60,000 characters!!!

**deano_ferrari** · 11-Sep-2019, 12:10

1. When wanting to share lengthy output, please use https://paste.opensuse.org/ and post the link that it generates here. That saves long posts of code output.

2. The HP Color Laserjet 2840 printer configuration shows that you're currently using a postscript driver (definitely not configured with HPLIP driver and backend), so scanning via the hpaio backend will NOT be possible as is....

Code:

device for hp_Color_Laserjet_2840: socket://192.168.169.141:9100

Code:

/etc/cups/ppd/hp_Color_Laserjet_2840.ppd.O:*NickName: "HP Color LaserJet 2800 Series Postscript (recommended)"

3. Was 'hp-doctor' not able to assist you with installing the missing dependencies?

**Budgie2** · 11-Sep-2019, 12:15

Hi Deano,
Will use paste site for the long output but meanwhile I had a good go at installing the missing dependencies. Here is the output from hp-doctor now. I do not understand the DBUS comment and the other dependencies were not on the repos I have installed but here goes:-

Deano I have posted the output from your earlier command. Here is the link:-

https://paste.opensuse.org/52530742

Hope this means more to you than me.

On your remark about the driver being postscript this was "recommended" and there were only postscript drivers offered.
As I mentioned on my Leap 15.0 installation the printer did not appear at all. I must have something wrong with the installation unless the drivers are on the community repos.

OT. Finally are you working very early or were you up all night? My grandson just started the football season in NZ and I had a great picture from him on the pitch and it wasn't raining!!!

My observation was from reading the lpstat output (for CUPS backend details and status), and the ppd details showing which driver is currently configured. As your thread title is about scanning, I wanted to shed light on why that isn't working for you, and it all has to do with HPLIP.

OT. Finally are you working very early or were you up all night? My grandson just started the football season in NZ and I had a great picture from him on the pitch and it wasn't raining!!!

It's morning here in NZ...was eating breakfast and catching up with forum posts.

There still seem to be some errors but await your advice.
Many thanks for all your efforts on my behalf.

That looks similar to the output I get (with a working HPLIP environment). Are you able to configure CUPS using the 'hp-setup' utility now?

I still do not understand why you advise the postscript driver will not work with hp-setup but the one I have is the only one offered for this printer and is marked as recommended. Does this mean it is the choice of driver that is the source of the problem? What about the crash handler. Are there clues there which would help?

From a printing perspective you're free to choose what works for you. However the scanner function depends on using the hplip driver for printing AFAIU. The 'hp-setup' utility will only help with configuring the hplip driver. (You've configured the postscript driver using YaST or CUPS.)

What about the crash handler. Are there clues there which would help?

I'll need more time to research this, or perhaps others can chime in here.
