Various sources (but not HP documentation afaics) suggest this printer is airprint-compatible. https://www.amazon.co.uk/Samsung-C480FW-Colour-Multifunction-Printer/dp/B010NE2HKI https://productz.com/en/samsung-xpress-sl-c480fw/p/wxnG7 If so, I would suggest "cannot delete" = continuous autodetection. What is the output of $ driverless As for not actually being able to print, I have a problem like that too which has only recently emerged with an airprint printer which worked until recently. You might find you can print (as I do) if you add a queue via lpadmin. As helped me recently: "# lpinfo -v to get a list of URLs (the one starting with ipp:// is the one necessary), and then something like # lpadmin -p Brother2740 -v IPP_URL_FROM_ABOVE -E -m everywhere" https://lists.debian.org/debian-user/2022/06/msg00212.html
