Xsane: Failed to start scanner: invalid argument

I am going to assume you have an HP Deskjet 2543 and that you are
using Ubuntu 20.04. Is that correct?

First you need to connect the device to the network, Then get a terminal
and execute

  scanimage -L

Post the output here.

Hello Brian, thank you for replying so quickly. Two perhaps silly questions, (you'll excuse me, I'm just a "brave" normal user that manages to do many things with tutorials but I'm not an IT guy) to say the "network" is the same as to say the internet, right? When you say get "a" terminal means that there are more than one terminals in Ubuntu?

scanimage -L

Hello Mauricio,

There aren't any "silly questions".

By "First you need to connect the device to the network" I meant
connect by wireless (or ethernet). This is the local network, not
the remote (internet) network.

When I said "...get a terminal...", I was trying to be helpful. Some
users do not realise a terminal is normal on Ubuntu. Use
whatever you usually use.

Your scanimage -L output is for a USB connection. USB does not
appear to work for you with xsane or skanlite. How about
simple-scan?

It really would be best to connect by wireless (it is less work for
me!). The device's control) panel should help to do this.

Brian.

Ok, thanks Brian.

Isn't that Simple Scan that you mention Document Scanner, the one that comes with Ubuntu in the Utilities bunch of programs? If it's that one I was saying in my first post that it didn't work but now it does after following your advice of connecting the printer in wireless. I tried to connect it to the router but I'm not sure if I managed it (WPS button). I believe I am connecting to the printer directly as I do it from the "Settings"/"Wifi" window and I have to disconnect the connection to the internet wifi when I do that. What do you mean with the "devices control panel"? At the bottom left I have the 9 square points where I access to all programs but I don't see devices.

So now I can scan, which is great, but the situation is the same as in the beginning of the post with Skanlite and Xsane. I could get by with Document Scanner but to repair those two perhaps could mean to repair things that I messed in the terminal trying to get it to print and scan. One of those things could be the reason behind the fact that the printer doesn’t print now (it did at some point yesterday).

Hi Mao,

Can you follow below steps for xsane:

1.)px -aux | grep ippusbxd [To check whether the ippusbxd process is running or not ]
2.)sudo kill -9 PID
3.)cd /usr/lib/udev/rules.d
4.)sudo mv 55-ippusbxd.rules /home/apex/
5.) sudo service udev restart
7.) Restart printer
8.)select the device with hpaio:net or hpaio:usb options

And you can download the latest hplip 3.20.5 with Ubuntu 20.04 support
