La stampante è regolarmente collegata e viene rilevata da lsusb
La funzione copia manuale funge regolarmente, quindi non dovrebbero esserci problemi alla macchina.
Se provo a stampare o a usare lo scanner dal computer risulta un errore di comunicazione con la macchina (che viene ribadito da hpl-doctor).
Tentativi fatti invano:
-uso di kernell precedenti ;
-disinstallaziolne completa e reinstallazione di hplip:
-installare - seguendo alcune soluzioni trovate in rete - versioni precedenti del software, non riusciti per problemi di dipendenze.
