I tried to install the HP 1220C printer to my PC. However the resolution of the printer is 300 dpi while it should be 1200dpi. That is why I can't print banners using that printer. I tried to remove the software and delete the Hewlete Packard software from the registry. Then after by restaring the computer, I tried reinstalling the software again. However the resolution of the printer is still 300dpi. So how can I change the resolution of the printer to 1200dpi? So that I can print banners. As I said, due to the resolution, eventhough the printer tries to print banners (it shows in the printer status "printing" then after it shows "Deleting" soon stops printing) Or what mistakes am I having during installation that makes the printer to be installed with a resolution of 300dpi? I would like to thank you for your cooperation in advance.
