Hi Amarnath, I'm not sure I perfectly understood your last comment. However, after reading it I've been doing downloading and installing the latest HPLIP just following the instructions on screen (same instructiosn as reported in your link of the above comment). Also, I've been asked whether to install the plug-in and the installation seemed to be successful. However, I found an error at the end of the installation process so I'm not sure whether the installation crashed or did not complete properly anyway. See at the bottom of this comment all the lines that I copied/pasted from the screen. Last but not the least, I have one question: should I reconfigure my printers/scanners each time I install the HPLIP/plugin updates? Thank you so much.
