How do laser printers work if they don't use ink cartridges? Kitty prints out a LOT of craft stuff and I cannot afford to replace the cartridges as often as she would like to print.
They use toner, which doesnt dry out, comes out dry (no smears) --- You get exceptional page counts out of toner cartridges. Laser is much much faster and generally has much better resolution as well as being considered generally cheaper per page in cost. The downside is that they are more expensive to buy the machine and the machines are usually a bit bigger. Here is a good write up: Inkjet vs. Laser: Which Printer Is Right for You?
