This was the last drivers released for the Canon Pixma MP250 series of printers. The driver was released in 2012 and will work on Windows 2000/XP/Vista/7 operating systems. You might need to run the driver in compatibility mode if you have another operating system.
You will need to check the Canon website ofr more information if you are having problems with the printer and also see if they can assist you with another driver for a different OS. The printer still has a very good release value and there are still many units doing the rounds. It was one of the better printers Canon brought out.
