How many times have you needed to hit Print on your computer and you've realized that you're just not connected to a printer? Physically connecting your computer to the printer of course will mean picking your computer up, making your way to wherever the printer is, or wherever a computer is that is connected to the printer through Ethernet cable. Why on earth should anyone have to put up with this, when it's cheap buying and setting up a wireless printer?
Well, as Bruce Robertson from Pisys.Net explains, printers are just getting smarter everyday. A wireless printer – one that is able to connect to computers through Bluetooth or Wi-Fi – can be had for as little as $50. You can park the printer wherever it's convenient, plug it into the power, and you're good to go. It'll just show up on everybody's computer as a network destination, and anyone can just send print jobs. If you’re good with setting up a wireless printer, there is no reason to have to wire things up anymore.
Now, unless you have a very old printer, you never have to connect a printer directly to the computer it needs to print from. Nearly every printer out there has a regular Ethernet port. You just need to connect the printer to a Wi-Fi router that wirelessly connects to every computer in the building, and you'd have yourself a wireless printer just like that. But that isn't really as convenient as a real wireless printer.
In some buildings and installations, the router is located somewhere really inconvenient, sometimes in the basement or on another floor. To have to put the printer next to the router can make little sense in many places. Setting up a wireless printer is the only thing that would work. Once you have it, you could get your printer and every computer in the building to connect wirelessly to one another.
In some installations, wirelessness in a printer can make even more sense. Consider a small office where there is more than one printer – perhaps one that's an inexpensive color laser model, one that's a monochrome laser model, a couple of inkjet models for different levels of quality and so on. Everyone in the office would want to connect to every one of these printers at different times. A print server would be an excellent idea in this case. Actually, make that a wireless print server. To think of the kind of wiring you would need to do in such a situation if it weren't a wireless set up, fairly boggles the mind.
