I had no idea about this. I don't buy on credit, in person, and don't register products either so who knew this was possible? I had an HP but my computer crashed and when I tried to get the new computer to work with the printer, it wouldn't work. I tried the program download from the HP site for the model I had, no go. So I bought a new printer but not an HP, it's a Canon. It works fine. They used to sell the printers with the installation DVD, not anymore. 🤬
