Any device that connects to the computer, such as a printer, scanner, monitor, keyboard or mouse.
She's going to be using this printer for scanning and printing documents along with photos. Leo likes the Canon Pixma because it's really good for photo printing. They tend to go through ink fairly quickly though, and ink cartridges are fairly expensive.
Jim wants to scan some pages and then edit the text. Leo says that’s called Optical Character Resolution (OCR) and it will give you various results. It’ll never be perfect. ReadIris is the best OCR program out there.
Jeff runs Linux of his machine, but he can’t print. Leo suggests using CUPS. It supports most recent printers. So install CUPS, then your drivers and that should clear it up.
Marty is looking to get a Bluetooth headset for his iPhone. Leo likes the BlueAnt Q2. Plantronics makes good ones. There’s also the Jawbone. But Leo prefers to wear wired headphones as they don’t drop out.
Dave has an old HP laserjet and he's getting a new computer and is worried that he won't be able to use it. Leo says he can get a parallel to USB cable, but the drivers won't see it. One possibility is that HP makes JetDirect, an Ethernet connection for printers. Dave could instead get a Parallel port card to install in the desktop and that would allow him to see the printer.
Rudy can barely see his computer LCD screen. It’s very faint. Leo says that means the backlit light has failed. Time to get it fixed or look for a new monitor.
She could get an AirPrint compatible printer. HP printers are supported by AirPrint out of the box. She can also search in the app store for "AirPrint" and "Canon" (her current printer) and she might be able to find a driver that will run on her computer making that printer available to her iPad. The printer will need to be on the network or shared in some way, though.
