Printing/plotting equipment and service have various types of plans that can be very helpful to businesses needing to print a large volume of materials often. Contracts cover the cost of toner and all parts and service on the machines. For low volume offices, it may be more beneficial to your company to select a parts and service plan. Under this type of contract, you only pay for supplies and service when you need them. Businesses that often have a need for a large amount of copies are recommended to take advantage of professional printing services.
