2 AQA ICT AS Level © Nelson Thornes Types of data

3 AQA ICT AS Level © Nelson Thornes Things to consider When choosing an output device you must think about: Amount of room available Size of display needed Resolution of display needed Portability

4 AQA ICT AS Level © Nelson Thornes Things to consider Type of outputText, graphics or photographs Volume of outputThis will affect print speed required Size of media requiredLarge format printers cost more Range of media requiredInkjets have a wider range than lasers and dot matrix printers cope with multi part forms Cost Vs efficiencyHigh volume printers may cost more to buy but are cheaper to run
