Da quello che leggo qui
http://www.sane-project.org/sane-mfgs.h ... TT-PACKARD
con risoluzioni non superiori a 600dpi dovrebbe funzionare, ma non è così.
A PC acceso, accendo lo scanner e lo collego al PC tramite porta USB, poi avvio xsane 0.999, che riconosce lo scanner.
A questo punto, clicco su [Acquisisci] per avviare la scansione, ma tutto ciò che ottengo è una pagina nera.
Come risolvo?
Per maggiore chiarezza, aggiungo un po' di output.

ho provato anche con Simple Scan, ma senza successo: quello che ottengo, è una pagina nera.

l'utente fipanzer (che non accede al forum da Febbraio 2017) asserisce di utilizzare senza problemi uno scanner Hewlett-Packard ScanJet 3800, ma non scrive cosa ha fatto per configurarlo correttamente.

l'utente ha provato a scaricare i driver da qui
https://sourceforge.net/projects/hp3900-series/files/
ma, dopo un inizio promettente, non ha risolto il problema.
