HPLIP

hplip Can Not Find internet connection in Linux Terminal

Asked by Tom Mannoia

I have used my HP Envy 4520 on my Dell Inspiron 3670 for many years using Windows and several linux operating systems. All was working well until I did an upgrade to Kubuntu 22.04.

When I run the install in the terminal: sh hplip-32.2.run, the install informs me that I need to install dependencies. I select "yes" then I am presented with this error message:

INSTALL MISSING REQUIRED DEPENDENCIES
-------------------------------------
note: Installation of dependencies requires an active internet connection.

The install cannot access the internet from my Konsole. But I can. I can ping, I can get system updates, I can do everything else in Konsole, but not the hplip installation.

Is there a work-around I can use to fix this? I do need my printer

Thank you for your help

For Ubuntu 22.04 there is a modified HPLIP package available in the Ubuntu repositories (version 3.21.12+dfsg0-1).
Just install that version with
sudo apt hplip hplip-gui

Thank you for your help. I am able to print now. The actual command was sudo apt "install" hplip hplip-gui.

As I said, I can print ... but the device is still not recognized as a USB device and as such it can't scan to the computer. I have to play with it some to see what I can do.

Thank you for getting my printer working again. That was invaluable! I needed it and you came though in no time.

Sorry for the omission in the command that I gave, but you corrected it perfectly.

For scanning:
What output do you receive for the commands
lsusb
sudo sane-find-scanner

Thank you AGAIN for following up. I wasn't expecting assistance for this part, but I can sure use it. Thank you very much for reaching out

I was trying different things and installed 2 scanning programs: gscan2pdf and also xsane. Now, in the hplip toolbox, my printer _does_ show up as HP Envy 4520 Series hp:/usb/ENVY_4520_series?serial=TH7684H22G0660. But I still can't scan.

I get the following error message in xsane and also in gscan2pdf. When I use the Paperwork program, there is no "button" for scanning. I go to set-up/calibrate within Paperwork and the program just sits there until I close it.

Although it shows up in my log, I don't have hp envy photo 7800 series. That somehow installed along with the hplip set-up

I'm sorry, I referred to an error message in gscan2pdf and also xsane, but I forgot to paste it in my reply:

Error opening device: opening device 'hpaio:/usb/ENVY_4520_series?serial=TH7684H22G0660': Error during device I/O

Also, when I open the HP Tookit, I get THIS message: No Installed HP Devices Found

But I CAN print

What happens when you try using the 'airscan:e1:HP ENVY 4520 series [B579D5] (USB)' device in xsane?

My most sincere apologies. The errors were ALL my own. There is NO PROBLEM with the printer/scanner install.

As a matter of fact, it could not be easier to use this printer.

I was very frustrated so I did a complete re-install of Kubuntu 22.04. Doing nothing but the install, the printer/scanner was recognized and everything just simply worked.

My errors were caused by trying to run hplip- by trying to use the gui installer, etc. There is NO NEED to do that. The printer is already setup to work. Ubuntu installed it along with the OS.

Thank you for everything. I am sorry for all the confusion. Things simply work on a clean install.
