There are occasions when you might want to print text or graphics on both sides of the page. There are two options that are available for you. You can either use duplexors available on TheNerds.net or you can manually print the same paper twice. The duplexors can be attached to compatible printers providing them with duplex (both side) printing capability. If your word processing software supports the duplexor and you have that unit attached to your printer, you can easily print on both sides of the same paper in one pass. This helps save time and labor when one has to print both sides of many pages. It is not just about printing on both sides; the duplexors also help you print on both sides of the page with pinpoint accuracy. The registrations of the text or image on either sides of the page are accurate when they are printed using duplexors attached to the printers.
