I have Fedora 20, with Gnome 3 Classic, and have installed Okular to read and, especially, print pages from, .pdf files. I want to print only a few pages, but in my frustrated attempts to set this up I have created, unintentionally, two print jobs that start printing the whole document each time I turn the printer on. the only ways I know to stop wasting ink and paper are to switch the printer off or take the paper out of the feed tray. Any attempt to print anything at all just starts these jobs off again.If I try to use HP Printer Driver Manager to Reject (i.e. remove or delete) the print job I get a window saying that authentication is required, but no combination of Username and Password that I know of will work, and there is a small twirly please wait or working symbol that prevents me from closing the HP Printer Driver Manager window, and never goes away. The only way I know of to get out of this is shutdown in the command line to turn the computer off.Obviously I am missing something, possibly obvious, beyond my comprehension. Please can anyone help me out of this impasse, even by using different software?
How do i deal with HP Device Manager requiring authentication to remove print jobs?
