Printer Cartridge
If you’re someone who already owns a printer, you know that printer cartridges are where the companies make their money. That’s because a printer without ink is essentially useless. The companies know this, it’s like buying razors.
You can buy whatever razor you want, you spend the real money on the blades because you have to keep buying them.
A printer cartridge contains ink. Printing is done with a combination of black, cyan, yellow, and magenta inks. This combination allows the printer to hit just about any color imaginable with remarkable accuracy. The cartridges can be sold separately, which is a blessing to anyone who is particularly fond of a specific color.
Printer cartridges can easily outstrip the cost of the printer itself within a year if you use them regularly. The cartridges can cost upwards of 50 dollars each. That means it could set you back over 200 bucks just to get a new set of ink for your printer. Thankfully, under normal use a cartridge will last a long time.
