I do not have access to the laptop on which the 12.04 was installed now. That laptop has been taken to a different city. Basically the problem was that after working ok initially, after sometime the printer was never detected by the hplip program. lsusb command used to show the usb device of the HP printer but it was not detected by the HP program. Since the printer was not being detected by the installed hplip plugin, no printer detected used to be shown. K Singh On Tue, Jan 15, 2013 at 2:30 PM, Sarbeswar Meher <
