Finchè non installi il plugin, la tua stampante non funzionerà.
Hai provato ad installarlo con python2?

@saxtro » Leggete la documentazione .....

Pensi che io non sappia leggere! Per il file ppd purtroppo è come dico io. Per installare i plugin basta il comando, da terminale:

Codice: Seleziona tutto

hp-plugin

e seguire le istruzioni. Fai attenzione che per ora devi utilizzare i plugin della 3.20.3 e di conseguenza hplip 3.20.3 non ti reoccupare se ti da degli errori.

[paride46]

Ho eseguito tutto.
alla reinstallazione della stampante mi è uscita la richiesta di lanciare il comando hp-plugin (ho sbagliato?)
la stampante non va. Ho combinato un guaio?
riporto i risultati

The device you are trying to setup requires a binary plug-in. Some functionalities may not work as expected without plug-ins.
Please run 'hp-plugin' as normal user to install plug-ins.

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the
HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies
are installed to successfully compile HPLIP.                                    
2. Run-time check mode (-r or --run): Use this mode to determine if a distro    
supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball   
has the proper dependencies installed to successfully run.

Dovresti verificare se questi pacchetti esistono e se sono installati

- L'errore di python, che non ti permette di installare il plugin, necessario per stampare.

Codice: Seleziona tutto

...
File "/usr/lib/python3.8/subprocess.py", line 512, in run raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '('lsb_release', '-a')' returned non-zero exit status 1.
...

Qui pare abbiano risolto, eseguendo l'installazione del plugin in debug.

Codice: Seleziona tutto

pdb3 /usr/share/hplip/plugin.py

UPDATE: I managed to get this to work, but this isn't really an "answer" or even really a "solution". I figured I'd see if the python debugger would tell me anything new so I ran hp-plugin from that, with the command pdb3 /usr/share/hplip/plugin.py -i -g, and, uh, it just plain worked. It still doesn't work without the debugger, but at least I was able to get my printer working again. I still cannot tell you what's wrong (and there's still something wrong here), but maybe more data will help.

Pare una volta eseguito l'invio del comando, questo termina senza interruzioni ....


@Roberto Pontecorvi

@saxtro » Leggete la documentazione .....

Pensi che io non sappia leggere! Per il file ppd purtroppo è come dico io. Per installare i plugin basta il comando, da terminale:

Codice: Seleziona tutto

hp-plugin

e seguire le istruzioni. Fai attenzione che per ora devi utilizzare i plugin della 3.20.3 e di conseguenza hplip 3.20.3 non ti reoccupare se ti da degli errori.

Confermi di non averla letta, o di non averla capita.
Come dici tu è:

E' quasi una cosa normale, il file viene salvato in una directory che ha i permessi di root. Vai in quella directory e cambia i permessi al file.

Non devi cambiare i permessi al file, che ripeto, sono:
640 root:lp
è sufficiente aggiungere il proprio utente al gruppo lp. E' tutto scritto nella documentazione, è un problema noto sulle distro supportate dallo script di installazione, in cui l'utente non appartiene al gruppo lp.

* Is the user part of the lp group? Run "groups" in a terminal window and verifiy the user is a part of the lp group. If not, consult your Linux distro documentation on how to add the user to the lp group. In most distros you can run (as root): "usermod -g lp yourusername"

Paride scusa, anche per evitare richiami dei moderatori, ti spiace inserire i risultati dei comandi tra i tag "code"? Basta selezionare il testo e cliccare sul 5° pulsante da sinistra in alto nella finestra di scrittura del messaggio, quello con l'icona a forma di </>.

verificando io ora
il pacchetto 'python3-pyqt4' non è installabile perché non è esistente nella versione di ubuntu 20.04. Come invece è esistente la versione python3-pyqt5

Current contents of '/var/lib/hp/hplip.state' file:
Plugins are not installed. Could not access file: No such file or directory

nell'output del comando precedente vedo che nel tuo sistema non ci sono plugins installati per visualizzare lo stato.


C'è ancora un disuguaglianza di versioni tra il pacchetto hplip installati nel tuo sistema Ubuntu, (versione del repository - versione aggiornata)

Ho eseguito tutto.
alla reinstallazione della stampante mi è uscita la richiesta di lanciare il comando hp-plugin (ho sbagliato?)
la stampante non va. Ho combinato un guaio?

Ho disinstallato completamente HPLIP e reinstallato la versione 3.20.9
La procedura è terminata senza errori ma la stampante non funziona.
Mi chiedo se non sia il caso di segnalare il problema agli sviluppatori.

Qui pare abbiano risolto, eseguendo l'installazione del plugin in debug.

pdb3 /usr/share/hplip/plugin.py

UPDATE: I managed to get this to work, but this isn't really an "answer" or even really a "solution". I figured I'd see if the python debugger would tell me anything new so I ran hp-plugin from that, with the command pdb3 /usr/share/hplip/plugin.py -i -g, and, uh, it just plain worked. It still doesn't work without the debugger, but at least I was able to get my printer working again. I still cannot tell you what's wrong (and there's still something wrong here), but maybe more data will help.

Pare una volta eseguito l'invio del comando, questo termina senza interruzioni ....

Non funziona. Rimane in attesa. Ho dovuto fermarlo manualmente.
Ho aperto il problema sul sito degli sviluppatori, speriamo mi rispondano.
