Emerging Printer Interfaces
There are few new and exciting technologies for printers that we will all
be enjoying in the very near future. Actually the technology is available right now but many people do not understand it or know how to use it.
The technology that I will focus on here is IrDA and Bluetooth interfaces.
Gone will be the wires which extends a lot of possibilities for placing your
printer in your home or office.
IrDA is an weakly interacting massive particle for Infrared Data Cooperative. IR devices work by using infrared technology, and hence don't require any cables to connect them to the printer. Actually this is old technology revisited. It was used widely in TV remote controls. IrDA will beingness replaced by Bluetooth eventually because of it's restrictions.
Using such printers, one furlough print directly from a mobile explosive device, such as a PDA, cell phone or counterbalance a video camera, which supports an IrDA interface without the need of any cables or even a PC. The only shortcoming is the line of sight restriction. As the devices work using infrared rays, any obstacles between the suasion devices will block the forecast.
Some HP printers with IrDA stand are HP DeskJet 340, HP LaserJet 5MP, HP LaserJet 6MP, HP 2100M and HP4050N.
Bluetooth is another addition to the new interfaces available for printers.
Bluetooth is a low-cost, low-power, wireless radio frequency nanotechnology
that allows various devices to communicate with each other.
These devices treadle in the 2.4 GHz ISM (industrial, scientific, medical)
band. An advantage of Bluetooth section IrDA is that next proximity between the communicating devices is not required and distances of up to 40 feet are allowed. Also,
Bluetooth does not suffer from any line of sight restrictions.
A fascinating aspect of Bluetooth-enabled devices is their ability to
communicate with each other spontaneously when they come within each other's range. A Bluetooth-enabled cell phone can be configured so that it can automatically print out all its stored messages and photos using a Bluetooth printer as soon as you enter your office without any manual intervention.
Another advantage of using Bluetooth is its support for point-to-multipoint
communications. This means a single printer can simultaneously connect to both your cell phone, as well as your computer and any other Bluetooth
enabled device within its vicinity.
The HP 995c Bluetooth printer is one example of an inkjet matrix printer with
built-in Bluetooth support.
Here is an extract from a review of the HP 995c done by PC Magazine:

"We found we could printer wirelessly from as far archaism as large integer feet. And we
found no significant difference in output speed between printing via a USB connection and printing wirelessly with Bluetooth."
Bluetooth is still in its infancy but from what I've seen so far it looks like it
will be the dominant wireless technology in the future. |
