SOHO environments faced with the choice of buying a fax, printer, telephone, and copier generally bulk at the idea and opt for a three in one, or similar device which combines faxing, printing, document coping and phone services into one small unit. Buying each of these machines separately can be expensive, but doing so generally means each device will be a little more specialized then units which combine everything under one hood.
Samsung make the SF-531P 6-in-1 Laser MFP which tackles laser printing, document scanning, document copying, fax and phone services. All this comes with a price tag of about $300USD making it a pretty cost-effective solution for moderate document-volume environments. The laser printing is capped at about 600x600 dpi with 8 pages per minute, so if you tend to print significant amounts throughout the day a dedicated printer would be a good investment.
