Many attempts to download HPLIP all incomplete???

> Printer copies & prints OK.

LM20 has set up your printer for you. What's the problem? Why do you
need HPLIP?

Hi,

My computer tells me the printer is NOT connected
I have changed cables & USB ports.

Read the instructions https://developers.hp.com/hp-linux-imaging-and-printing/downloads

You should not open the hplip.run file with your editor, but you should open a terminal window and start the HPLIP installation with the command
sh hplip-3.20.6.run

But if the computer cannot identify the connection to the printer, then I doubt that installing additional software will help.

Do you see the printer in the output of the command
lsusb

I quoted what you said:

Does the printer print or not?

> Printer copies & prints OK.

Worked this out (possibly).

You use the copier, Printing takes place. You think this is significant.

It isn't. It has nothing to do with the Mint printing system.

Hi,

Yes, but as I said before, only from the printer using the copy function.

The computer tells me the printer is not connected.

Much appreciated.

Hi,

I understand that.

With the connection to the computer reestablished, the printer turned on.

Go printers & search for a printer.

Found my HP Deskjet 2621 & selected.

Attempt to print unsuccessfully.

Message displayed as: Printer not connected??

Say whether you are using a USB connection and give the outputs from

systemctl list-units "ipp*" | grep service
avahi-browse -rt _ipp._tcp
avahi-browse -rt _uscan._tcp
lpstat -l -e
lpstat- t
driverless
lpinfo -v

Hi,

I am not into programming so have no idea what:

systemctl list-units "ipp*" | grep service
avahi-browse -rt _ipp._tcp
avahi-browse -rt _uscan._tcp
lpstat -l -e

driverless
lpinfo -v

I am using a USB connection which is telling me there is no connection to
the printer.

I have installed a thumbdrive into this same USB & it reads fine.

There must be something within Mint 20 which is causing the problem.

I did experience problems with the printer when I first installed upgraded
to 19.3.
I do not remember what I did to overcome the problem.

Open a terminal window (e.g. by simultaneously pressing ctrl-alt-t) and issue the following commands, one by one when the printer is plugged into the USB port and powered on:

lsusb
systemctl list-units "ipp*" | grep service
avahi-browse -rt _ipp._tcp
avahi-browse -rt _uscan._tcp
lpstat -l -e
lpstat- t
driverless
lpinfo -v

Then use the terminal window's menu entries "edit - select all" and "edit - copy" and paste everything into the "Message:" box of your question document https://answers.launchpad.net/hplip/+question/691936

Hi,

All went well until I entered:

alan@alan-Lenovo-ideapad-330-15IKB:~$ lpstat- t

Command 'lpstat-' not found, did you mean:

  command 'lpstat' from deb cups-client (2.3.1-9ubuntu1.1)
  command 'lpstat' from deb lprng (3.8.B-2.2)

Try: sudo apt install <deb name>

Tried again with the same result???

More assistance appreciated.

Sorry, it seems that there is a typo error in the commands.

It should have been

lpstat -t

Hi,

Amazing, my printer is now functioning again.

Very much appreciated.

Good. Now, please mark this thread as "solved" to help other users.

Amazing, my printer is now functioning again.

Very much appreciation to all involved.

I was at a total loss of what to do.

Thank you all.

Hi,

I do not understand?
Now my printer has refused to cooperate once again?

I have I believe done as requested as follows.

alan@alan-Lenovo-ideapad-330-15IKB:~$ su -c 'journalctl -u cups.service --since="2020-07-25 07:50:03" --until="2020-07-25 07:51:30"' > trouble
Password:
su: Authentication failure
alan@alan-Lenovo-ideapad-330-15IKB:~$ abc123
abc123: command not found
alan@alan-Lenovo-ideapad-330-15IKB:~$ printer
printer: command not found
alan@alan-Lenovo-ideapad-330-15IKB:~$ su -c 'journalctl -u cups.service --since="2020-07-25 07:50:03" --until="2020-07-25 07:51:30"' > troubleshoot-logs.txt
Password:

alan@alan-Lenovo-ideapad-330-15IKB:~$

Would appreciate any assistance.

As far as I know with Linux Mint you shouldn't use su, but sudo

Thanks!

Hi,

Believe it or not.

I disconnected the printer, connected an older printer of similar breed etc.

Started the printer & it installed automatically.

Printed a Test page no problem.

Printed a simple page from the computer & no problems.

Weird but wonderful.
