Toner replacement cost is $457. for four cartridges. A new printer with cartridges included is $548

[nonbene]

Four toner cartridges coat $457.00. A new printer with four cartridges included is $548.00. Why not buy a new printer each time to replace cartridges and re-sell it? Would be much cheaper. I shall throw the printer out and buy another product before I will pay 80% of the cost of a new printer to replace toner.

Because the toner cartridges that are included with the new printer can print fewer pages than the ones you buy after.

Depending on the printer model included toner cartridge can print 800 pages but the cartridge you buy later prints 3000.
