Computer printers are an essential piece of equipment for almost every company. A modern computer printer can print everything from simple letters to brochures, flyers and now — with the emergence of 3D printers — solid objects such as prototypes. A scanner works like a photocopier, but the image is loaded straight into a computer.
There are a few key questions to ask yourself when choosing your printer:
You should consider each of these factors when determining your requirements for a computer printer.
There are two main types of computer printer:
Inkjet printers produce vibrant colours and realistic photos by spraying ink onto paper. Slower and with higher running costs than laser printers, they are best for a single user and light use.
Other types of computer printers include plotters, which are used to print posters and banners, dot matrix printers, which use old technology but work well in dusty or dirty environments and — at the other end of the spectrum — the new kid in town, 3D printers which can be used to realise and print 3D designs. Still in their early days, 3D printers can allow designers, entrepreneurs and engineers to design and create 3D ideas, prototypes and fully formed products.
Unless you print only a few pages a week, a laser printer is probably your best option. Small models cost from £50 and are suitable for up to five people, depending on how much they need to print.
Larger laser printers are more expensive (from £500), but are designed to be connected to your business network and shared between many people. Buying one heavy-duty printer usually offers better value than purchasing several smaller ones.
If you intend to share a printer between users, look for a model you can plug straight in to your computer network. An increasing number of printers offer wireless networking too. This allows the printer to connect to your wireless network and is useful if there’s no network point near your printer.
All-in-one devices print using either laser or inkjet technology and also offer fax, photocopying and scanning functions. They save space and usually work out cheaper than buying separate pieces of equipment. Basic models start under £200 and are best used with a single computer.
A high capacity all-in-one device, with laser printer, fax, photocopying and scanning capabilities and able to print 120,000 pages a month might cost £3,000.
These heavy-duty computer printers are expensive, so you may wish to lease one instead of buying it outright. Leasing agreements often include regular servicing and upgrades to newer models, so can be very cost-effective.
Over a printer’s lifetime, the running costs of your printer will likely total much more than the up-front price. Many manufacturers often give a cost per page to demonstrate the likely cost. These can be on the optimistic side, but offer a good indication when compared with each other. You can also calculate printing costs yourself.
Inkjets tend to be expensive to run – from about 3p for a page of black text up to 50p to print a full-colour photo. From about a penny for a page of black text, lasers are almost always a cheaper option.
Computer scanners have several uses:
Once you have scanned an image, you can also use graphics software or a video editing package to edit the resulting file on your computer.
The type and size of documents you want to scan are key to your choice of scanner. Most scanners will work with PCs and Macs, though you should always check.
A basic A4 flatbed scanner will cost £50 or so. A larger scanner will be much more expensive, so if you’ll only occasionally be scanning big items, it might be best to use a scanning service.
The resolution of a scanner indicates the quality of image it will generate and is measured in dots per inch (DPI). The higher the DPI, the better quality the image. However, manufacturers often quote an inflated 'interpolated' resolution – ignore this and always look for the 'optical resolution'.
If you plan to archive documents, get a document scanner with a paper feeder to scan multiple sheets automatically. Some scanners come with optical character recognition (OCR) software which recognises text on paper and converts it into text you can edit on your computer.
Decide what you want to use the scanner for and how often you expect to use it. This will help focus your mind on the features you require.
