For some reason, the older 'workgroup' laser printers are selling for pennies these days.
An online auction has three of the HP 8150 DN Network ready laser printers for sale; opening bid $50 and nobody has bid -- auction has been up for one week and is over in one hour.
The "DN" specification means that it has the optional Duplexing module and the Network interface installed. Duplexing is fancy printer talk for printing on both sides of the page with no operator intervention needed. These puppies sold for $3K to $5K just a few years ago -- they are fast, absolutely bomb proof, can print up to 11X17 pages, gorgeous image quality (black and white only through...) and your page costs are less than a penny for operation.
Compare this to your desktop inkjet printer which has its place but... they are s....l......o.........w............... compared to the laser, limited to 8.5X14 page size and cost per sheet is about 5¢ on up depending on coverage. If I didn't already own four of these beauties, I would snap up these three and give them a good home. Fifty @#$% bucks for an incredible printer...
