I do love "wireless" and wish more equipment that is used in the home (or office) is wireless. I wrote recently about irons, and the fact that there is an element of wireless. The iron itself is wireless, and sits on a "base" to heat.
I have had a wireless printer for some time. I use a Brother laser printer for most of my work, and get my toners from Hot Toner, which arrive quickly after one orders. The last time I bought a toner was 2 years ago, so I will be interested to see how long this order lasts. (I get 2 at a time!)
The Brother is quite a few years old, and yes, it has cables. One connects the computer to the printer, and the other cable is the power one.
I don't do much colour printing, as I get all my photographs printed at Officeworks or Harvey Norman. The Epson printer is "wireless" but I have not managed to get it to do so. I gave up a long time ago. I've always attached the two cables. However, a couple of weeks ago I got a bit annoyed about the issue, and played with the printer until it worked. Yay.
I am often challenged with either technical stuff, or "men" stuff. Having to put things together is always a challenge for me. As I am on my own, I have to deal with it.
Luckily both my printers are working well, so is my camera, so all is well.
