Hi Consuelo,
Error 1203 is an issue that occurs either when a cartridge is bad or the printer cartridge Slot is bad.
I would suggest you to try cleaning the copper contacts of the both cartridge and cartridge slot in the printer using either a pencil eraser (gently) or a little denatured alcohol on a cotton swab and then try printing again.
If this does not help you may have to have the cartridge replaced at the store you bought it from.
Hope this helps
Eric
