Laser printers are very complex compared to inkjets, and will cost more for the same pending on the volume, personal laser printers should do well for most people.but it is worth checking out Ebay for printers that were designed for workgroups.they will always last longer.little over a year ago, I picked up a kyocera 1700 with a 3000 page count for $50 +25 shipping.toner needed to be replaced but other than that it works great.and it is rated for 200,000 page life cycle.High Yield Value Pack of All (4) Toner Cartridges for HP Color LaserJet CP4525 Series (HP 649X/648A Set) Laser printers use completely different technology.the main tech behind laser printers is positive and negative varies from printer to printer which charge is being applied to which compnent.the black printing you see is from toner, which is basicly tiny plastic beads colored black.toner CAN go bad, if exposed to heat, causing the plastic beads to melt and clump together.however, if stored in moderate temparatures (70F), it should last forever.with a laser printer, there is a light sensitive has a uniform charge placed on it, then the laser draws either the desired print job or the inverse of dsired output on the drum.either way, the result is that toner will stick to the drum only where it is supposed to.the toner image is transfered to the paper (which also gets a uniform charge) and then the toner is fused into the paper by the fuser (heat and pressure melt the beads into the paper, making it permanent).

If you need color, all bets are off (unless you have the cash to buy a color laser). ![]() Inkjets are about $80 for the 2 cartridges and in my experience last about 3 months before it evaporates if I don't bag them no matter how many pages I print, and ink cartridges are rated to about 500 pages even if evaporation isn't a factor. At $75 a cartridge, that's a pretty good deal. ![]() If you are printing an average of 10 pages a business week, a laser cartridge lasts about 300-600 weeks, or 6 to 12 years. Most small laser printers have cartridges good to 3000-6000 pages at 5% fill (a typical business letter on 8.5"x11"). They still had the printer it was made for (in the museum at Palo Alto) and the darn thing worked after a good shake. Laser cartridges can store at least 20 years - that is a fact HP discovered accidently, they came across a sealed cartridge that had been lost in a warehouse for two decades. all bets are off on an Epson), but the nozzles still clog. storing cartridges in sealed freezer bags with a damp paper towel (assuming it's an HP, Canon, Xerox, etc. Absolutely laser if you can afford it and don't need the colour. ![]()
