An inkjet printer will cost from $30 and up, while a laser printer will cost $80 and up.
A scanner allows you to take 'photographs' of objects and documents. The most common use for scanner is to copy documents and images and save them to your computer. Most scanners are flat and sit on a desktop. When you scan a document, you receive a digital image on your computer that can then be converted to a text file and edited. A good quality color scanner will cost around $100.
You can purchase a combination printer and scanner that generally will include a copier and fax as well for around $150. This is by far your best option and you will save office space with these compact, all-in-one machines.
