Have you ever printed on both sides of the paper in just to save paper?
A lot of home and small office printers are unable to to print on both sides of the page. Whilst it is your intention to save paper and be environmentally responsible, which is a admirable quest, printing on both sides of the page on a non duplex printer can be costly and chew up more printer ink toner than single sided printing - (called simplex printing).
Try to imagine the mechanics of a laser printer. Paper feeds in, toner is then magnetized to the drum (based on the information sent from the computer, toner gets rolled onto the paper and the paper feeds through the mechanical belts and rollers arriving at the fuser unit a component that melts the toner to the page. Finally the printout feeds through more rollers and belts to the printer tray.
when you turn the paper over so that you print on the opposite side with a printer that is not capable of duplex printing, after the paper gets to the fuser unit it heats the toner on BOTH SIDES of the page. Melted toner can then be deposited onto the rollers throughout the printer. Printed pages could have words ghosted on following pages which results in that the whole project can be a waste. If the problem is bad enough, it is possible that have to replace the printer.
By heating a piece of paper, can cause also the paper to curl slightly on the edges. Printing essentially modifies the composition of the paper. Non-duplex machines can often get jammed with page that has already been printed on. Resolving a paper jam is time consuming and distracting, and can often damage the printer or toner or printer ink cartridge, especially if the paper tears and a piece gets left behind. Damage to the sensitive drum or rollers also happens when paper jams are not removed carefully.
Similarly, the problem arises with inkjet printers. Ink takes longer to dry than toner, and streaks of wet ink on the printer rollers may cause streaks and lines on the pages that follow, resulting in a non professional result and wastage.
If you are looking to purchase a new laser or ink printer, and you would like to print on both sides of the page, most brands of printers have the letter D in the model number to show that the printer is a duplex-ready printer. A duplex printer has the correct mechanics that removes printing problems issues like streaking etc. on the paper.
You may wish to check your printer manual to see if the printer is an automatic or a manual duplex. Manual requires that you will need to flip the pages over yourself and re-feed into the printer paper tray when instructed to by the printer. However, In contrast, an automatic duplex printer has a mechanism inside that turns and feeds the paper back into the printer without needing human intervention.
