A printer looks inexpensive until you add ink, paper and the cable your setup requires. Another model may cost more upfront and meet the same need differently.
Write down what is included and what you must buy separately. Check official specifications for compatibility. If replacement supplies are part of normal use, look at their current prices and availability without assuming that every advertised saving will apply to you.
Compare the same setup
Build a comparison around the use you expect. An occasional home document and a large weekly printing job need different assumptions. Include space, maintenance and the practical option of using a service instead of owning equipment.
Keep the calculation simple enough that you can explain it. You do not need a precise lifetime cost forecast to notice a mandatory accessory. If a seller cannot confirm what is in the box, ask before ordering. Save the answer with the purchase details so that you can check the delivery against what you expected to receive.
