i am trying to install the hp officejet 5740 e-all-in-one on ubuntu 14.04. Using the lsusb i can see that the printer is connected to the USB:
Bus 002 Device 005: ID 03f0:cd11 Hewlett-Packard
and i can install the printer from the system setting, which however gives me Officejet j5700 Series, hpcups 3.14.3 as the printer make and model although i selected several times officejet j5740, which is the most similar name i get from the list. the defaults seems to be indeed the officejet 5600.
I can print the test page all right but then, when printing a file, the page is offset thus the printer is useless. this not to talk about the scanner and fax.
using the hplip -- which i have installed from the software centre and is marked 3.14.3 -- no printer is identified from any port, specifically on the USB. Before I was using the HP 2540 which was correctly detected and managed by hplip. I also tried to install the hplip 3.15.2 from terminal but my superuser password is not recognized.
how can i properly install the 5740?
