Print error message after Ive printed 3 pages successfully

hi! I was printing happily with my C43SX printer at 3 pages of draft output printed successfully, when suddenly when I tried to print in Photo+text option I get a print error message.

I've tried everything-from turning off/on my printer, restarting my pc, getting online and offline settings from control panel, but this message to install a device driver software keeps popping up fr Windows Vista admin, telling me to install drivers.

I dont understand what suddenly went wrong, if I've been able to print a couple of pages previously? Help pls!Thank you so much
