I saw this this question and followed its answer, but the problem persists for me. Once I send a document to print, this dialog box (in figure) opens up and shows "Held for authentication". Then I right-click and enter my username and password and then the pdf is sent to the network printer.
Is there a way to store my username and password? The 'Remember password' option does not work. I do not want to remove authentication (can't see how the network printer will identify me if I am not authenticated, as the network is based on Windows), I just want to save my username and password into some appropriate file so that I do not have to key in every time.
