- Choosing an output device
- Monitors and screens
- What kind of image needs to be viewed
- Graphics designer, web designer, or architect will need a large screen with high resolution.
- Most office users will be working with text primarily so won't need too high resolution.
- Where is it going to be viewed?
- Car - e.g. satellite navigation - needs to be large enough to show clear images so the driver can easily see where they need to go.
- Mobile - e.g. mobile phone - needs to be small enough to be comfortable to carry around, but large enough to display text and images clearly.
- Dirty situations - e.g. factory - needs to be protected from environment. May require a stronger non-reflective screen.
- Who is going to view the image
- Partially sighted users may require a bigger screen than usual so that they can see more of the page at once on high-zoomed settings.
- If the picture is going to be shown to a lot of people at once, an interactive whiteboard may be a useful output method.
- Internet access
- No control over who sees it, so they must consider everyone.
- Website may look good on a large high-resolution monitor, perhaps not on a smaller screen.
- There are very few situations where a screen of some kind isn't needed. The main issues when deciding which one to use are the size and resolution.

- Printers
- What is to be printed?
- If the print output is mostly black text, then a monochrome laser printer will be most suited.
- If colour is used frequently, either use an inkjet printer or a colour laser printer.
- Laser printers are generally more expensive initially than inkjets, but cheaper to run.
- How many documents?
- High volumes are handled much more quickly by laser printers, and they also have larger paper trays so that they do not need to be filled up as often.
- What kind of media?
- Most printers are designed to be mostly used with A4 paper. Larger paper sizes need larger printers, which tend to be expensive.
- Inkjet printers are generally more versatile regarding specialist media, such as high-gloss papers, textile printing transfers, metallic or plastic films, or even special sheets of cotton or silk.
- Who is to use the printer?
- If a printer is to be shared between multiple users, it will need to be networked.
- Can also be connected using bluetooth or network cards.
