For example, a "DeskJet 5510" will use a "DeskJet 5500 Series" driver. In general, you "round down" the model number that appears on the case of the printer to the next lowest number that is available in the software.</li> <li>If this doesn't work, visit this page and follow the instructions to download and install a new PPD file for your printer: <a class="reference" href="http://linuxprinting.org/">http://linuxprinting.org/</a></li> </ol> <p><strong>Issue 2: Printer still does not show up in CUPS after restarting.</strong></p> <p>Solution:</p> <ol class="arabic simple"> <li>Check and make sure that the printer is connected to your system and powered on with no printer errors.</li> <li>Unplug the printer from your computer, open a terminal/console window and enter this command.</li> </ol> <pre class="literal-block"> tail -f /var/log/messages </pre> <p>then reconnect the printer.
