Is A Laser Printer Right For Me?
The average home computer user definitely does not need a laser printer. Sure laser printer prices have fallen considerably in the last couple of years. But have you look at the cost of laser toner? The average laser toner cartridge sells for over $100. The cost of replacement ink can really ad up on you. Cost of ink should not be the only factor that deters you from buying this kind of printer though.
Drop On Demand Printers
Most HP and Epson printers are drop on demand printers. They use electrical pulses to fulfill requests for ink. The ink is expelled out of the print head by a bubble which forms as a reaction to being heated. Once the ink is propelled out of the cartridge, the bubble cools, contracts, and forms a vacuum of sorts, which pulls more ink into the nozzle.

Laptop Security -Where?d My Laptop Go?
Laptops are lovely. They are convenient, mobile, powerful and prestigious.They are also thief magnets. Over 400,000 laptops disappear each year, leaving their owners wondering where they went, what is happening with their data and what to do next.Some of the laptops are just lost ? left in cabs, at hotels, restaurants and at conferences and events. Many of these laptops (but not all) find their way back to their lucky owners.Some are stolen by people ? many of them co-workers, service staff or people taking advantage of a ?moment of opportunity? ? who just want to have a laptop.Some are stolen by professional ?Laptop Lifters? who may work in teams to steal the laptops for resale.And others are stolen, not for the laptop itself, which may be a bonus, but for the data on the laptop?s hard drive ? financial or identity data or business plans or data.For example:QualComm?s CEO had his laptop stolen while he was conducting a Press Conference. Reportedly, some of QualComm?s most valuable secrets were on that laptop, unencrypted and only protected by an easily bypassed password.A Department of State laptop containing high level information on nuclear proliferation was stolen right from State?s headquarters. Two administrators were fired and other personnel were reprimanded.Think about it ? What other piece of equipment or personal possession do we routinely carry around that is worth over a thousand dollars, by itself, and may be worth thousands more in data? Why wouldn?t that be attractive to thieves?A large part of the problem is less on the hardware or software end of things, it?s in the HUMAN side of things. By raising our awareness many of the vulnerabilities can be greatly lessened.There are 3 areas of vulnerability: 1) Securing the actual laptop, 2) Securing the Data, 3) Getting the laptop back.
