Once you have bought your PC and printer, you will need to buy a steady supply of blank floppy disks for the PC, and paper and ink or toner for the printer. These are the consumables and can easily cost as much as the basic equipment over the course of a couple of years. When choosing a printer, look to see how much the consumables for this particular model will cost. If you are choosing a laser printer you will need to replace the toner cartridge (which contains dry, powdered ink) after a few thousand pages. After a couple of years of heavy use, you might also have to replace the drum (which is used to create the image). For an inkjet printer it's cheaper, since you only need to buy new ink cartridges, but these will only last a few hundred pages.
Before you buy a new printer, look at the cost of a new toner or ink cartridge and how many pages they will last before they need to be replaced. If you plan on doing a lot of printing, you might find that a cheap printer will cost more in the long run because of expensive consumables, and that you may not be saving any money in the long run at all.
