The sell things like Printers Scanners Fax { you can get 4 in one printer/scanner/fax/copier}
Cameras Inks
The numbers are clearly marked on the side of the box of Ink what you need for your model
They often come on special at places like Big W
No point getting the cheapo inks ones I have heard they are often only 3/4 full or not as good
If you get them on a good special grab a couple you will prob use more colour than black but you can change it to plain paper instead of paper pro in the maintance section
You get the same great quality it just uses the black ink only
You can change it back at any time
