HP designates their toner cartridges as 'A' (regular yield) or 'X' (High yield). Some of their products do not offer a high yield cartridge for specific machines. Know what your buying before you decide "this toner cartridge is cheaper".  Your 'cost per page' (CPP) is better with high yield toners.

        Inexpensive/ discounted/ cheap paper, is the number one reason for printer repairs and cleanings. If you buy this type of paper, all the money you saved will be paid to the technicians to keep your machines from jamming. Copiers, printers, fax machines.  They all move paper at different speeds. Lint from your 'cheap' paper collects on the rollers and impeeds the movement to the next sensor or roller.  False paper jams can drive you nuts!  Do yourself a favor and buy a better quality paper.  Just because it's 'paper' doesn't mean you can use it in your machine. Know the paper limitations of your machines, before your start ordering custom letterhead and business media.  Improper print commands from your computer to your printer, is another problem that initiates service calls. " My printer is broken, every time I print on this media, it smudges." The newer 'instant on' machines need computer commands to tell it how fast and what tempurature to melt the toner onto you media. Know your printer limitations!
