Computer hardware for business
Printers, scanners and multi-function devices
If you have several computers and peripherals (such as printers and scanners), to get the best from them, you should network them together.
Sharing printers over a network
A computer network allows you to share internet connections, data and resources within your business, improving both efficiency and speed of working.
Originally, all computer networks used fixed wiring to link PCs and peripherals. However, many businesses now have wireless networks - which are ideal for workers who need mobility - or wired networks with wireless hubs in shared spaces.
Types of office printers
Printers are essential for most businesses. There are three basic types of printers:
- Laser printers produce colour or black print and are suitable for most office printing needs. They are more expensive than other types of printers but are more economical if you do lots of printing and are relatively fast.
- Inkjet printers can carry out either colour or black printing. Some inkjet printers can produce photographic quality images. Although cheap to purchase, inkjet supplies like paper and ink make them expensive per page printed. They are also slower than comparable laser printers.
- Impact printers, such as dot matrix printers, are now rarely used except for special purposes, eg for printing forms used with accounts packages.
You can connect printers directly to desktop PCs and laptops, or share them on a wired or wireless network. Shared printers are preferable for most small offices, but some workers may need a personal printer in a secure location, particularly if they are dealing with sensitive or confidential information.
As with most computer equipment, unless you have in-house expertise, it is worth paying for a maintenance contract for your printer. Access to the right support can help reduce disruption and downtime in case of any equipment failure. See more on hardware installation, maintenance and support.
Scanners are used to capture images digitally. They can be useful in an office for storing content digitally that is only available in print and for extracting text from documents such as books. You can connect scanners directly to a desktop PC.
Multi-function devices: advantages and disadvantages
A small office usually needs a printer, a photocopier and perhaps a scanner. These can be combined in one multi-function device. They have several advantages:
- the total cost may be lower than the combined cost of separate units
- they save floor and desk space
- there is less to install
However, such devices may not deliver all the performance available from separate units and, if they fail, you may lose all the functions at once and will need to replace the entire unit.
