You need a printer, so you go to the store.
The inkjet printer industry offers you an all-in-one printer/ scanner/ copier with 1200dpi printing for $65. It includes "3 months free instant ink".
The laser printer industry offers you a printer with 600 dpi colour printing, no scanner/copier function, and it costs $265.
You ask the nice young man in the store which is better. He tells you the inkjet gives the best quality for printing photos, and the laser printer is best for business use and people printing 500 pages per week or more.
So you buy the inkjet. Repeat 3 years later after it stops working.
