Any device attached to your computer is referred to as a peripheral, be it a mouse, printer, scanner, tablet or whatever.
Thankfully, we rarely have trouble with our peripherals as they usually work fine straight out of the box, and that's the way it should be. Nevertheless, in our imperfect world, things do, and will, go wrong. Sometimes, despite a manufacturer's best attempt to provide a silky smooth installation experience, instead you are left tearing your hair out. Increasingly complicated devices such as 'all in one' printer/scanner/copier/fax machines, which of course must connect wirelessly, have become the norm. Fabulous machines we all agree but often are the devil to set up, especially in an office shared by multiple PCs and Macs.
If you've reached your wit's end with the user instruction manual and time isn't on your side, we can very possibly help.
