Terry Ashwin invented Send-It in 1990, allowing printing and printer sharing between computers.
SEND-IT, an approved, locally manufactured product, is a cableless data transceiver device allowing printing and printer sharing between computers, whilst eliminating the need for cables. Data transmission is achieved by means of radio transceivers attached to P.C.’s. workstations, or file servers which communicate with one or more uniquely-identified printer base stations, each of which can control up to three parallel printers.
SEND-IT units connect to either the serial or parallel ports of the computer terminal. The former (serial) conforms to MS-COS standards, whilst the latter is Centronics compatible and is driven via the parallel port, thus being software independent. Both types of units address the same printer base solutions thus allowing the sharing of printers from a wide variety of workstations.
SEND-IT has a range of approximately 25 metres. This can vary according to the construction of floors, walls and ceilings but in an open-plan office the range would exceed this. The only limitation in terms of the number of terminals and printers in a system environment is the range.
SEND-IT Incorporates a transmission protocol which detects and rejects corrupt data and will only allow uncorrupted data to be printed. Security is achieved by the use of a unique transmission protocol, and coded printer base stations.
The large increase in the number of personal computers in use has seen a proliferation in the requirement for cabIing. Even the so called portable computer is still dependent on cabling to operate printing. Cable installation is expensive, inflexible and disruptive, and as more and more peripherals are added, so the complexity and volume of cabling increases.
This has created a market for a product that will eliminate the requirement for cables In the personal computer and main/mini-frame environments.
Applications Dependent upon Cables
Common to all, is the cabling required between the components of the system.
