Printer ink can be expensive and messy. 

Luckily, most inkjet and a few laser toner cartridges can be refilled at a low cost. Companies like Costco sell one-hour inkjet refills, for instance. Also, refill kits are available for the DIY folks. However, refilling inkjet or toner cartridges is messy and not for people who are mechanically challenged.  Before you buy a printer/copier, make sure to check the manufacturer’s published cost per page. Volume Many small business-oriented printers/copiers aren't built for heavy volume. Be sure to check the unit's recommended usage. The ISO yield for the ink/toner cartridges will provide you with some idea of how frequently the cartridges will have to be replaced. Even if you have an in-house printer/copier, it might still be a good idea to use copy and print services, like Kinkos or Staples, for big copy and print jobs, as well as specialty printing like brochures.  With the price of consumables, it is just not cost-effective to do huge volume copying and printing on inexpensive printers/copiers, especially with photographs or color documents. Buying a low-cost printer/copier for basic needs and outsourcing larger print/copy jobs is the perfect compromise for many small businesses. ​ Duplexing Duplexing is the capability to print/copy on both sides of the page and is a very desirable feature. In addition to saving paper, it is a must for creating professional copies of the two-sided printed material. Connectivity For using the product as a printer, the more ways to connect to the machine, the better. In addition to direct USB connectivity to a PC, most printer/copiers possess network connectivity including WiFi, wired, or both. If you want the printing from the cloud or from mobile devices, be sure that your printer supports technologies like Apple AirPrint or Google Cloud Print.
