The biggest question is whether you should get an inkjet or a laser printer. It depends on your needs. If you plan on printing a lot, the toner in laser printers lasts a long time, but the replacement ink can be pricey. The color on laser printers is much more vibrant than an inkjet. However, inkjet ink is relatively inexpensive but plan on replacing it often. Inkjets also print photos better, so if you use photography in your printables, that is something to consider.
For maximum efficiency with cutting printables, consider in investing in a cutting tool like the Silhouette Cameo or Cricut Explore. Both allow you to print out any shape and cut around the printable. It takes minutes to set up the file and cut compared to hours of using scissors.
