The Canon B203 error code is a printer error that occurs when the printer is unable to read the ink cartridge. This can happen for a variety of reasons, such as the cartridge not being properly seated in the printer, the cartridge being empty, or the cartridge being damaged. If the error code occurs, the printer will usually display an error message on the screen and will not be able to print. In some cases, the printer may be able to continue printing after the error code is displayed, but the quality of the printouts may be poor.
