Question
How do I buy a new heating system?
Answer
Typically, ink cartridges are very expensive. Many people, therefore, use compatible ink cartridges (those made by a company other than the printer manufacturer) that give comparable quality, but with considerable savings. Another alternative involves modifications that allow the use of continuous ink systems that use external ink tanks. Some people choose to use inexpensive ink, knowing that, in the long term, it may damage the printer. However, the cost savings of 4 or 5 refilled cartridges may well be sufficient to pay for a new printer. If the printer lasts more than that, they have obtained the same result (economically speaking) at a lower cost than using original supplies.
