|Basically it is the brand name of that company. All Inkjet technology is basically the same. As was pointed out Laser printers are better.|
You need to look at the total cost of ownership when buying a printer.
It works kind of like buying a Cell Phone. You get it cheap but need to sign up for a 2 year plan. Each month of that plan you pay part of the subsidized price for the phone.
Inkjets and to a lesser degree, smaller laser printers work the same way. Then sell you the printer cheap but force you to buy their supplies. Eventually you pay for the printer and then some.
Don't believe the number of copies per cartridge either. They usually base the copy numbers on 5% sheet coverage. When printing in color you will usually exceed that percentage by a lot.
One last thing to note. Most new printers come with "starter" cartridges/toner. This is a euphemism for no product in the cartridge. Be a smart shopper.
