Smart Label Printers
SLP-4AST is a proprietary technology developed and used by Seiko Instruments USA, Inc. (SIU) for their line of Smart Label Printers. It is a data transfer protocol for sending and receiving data between the printer and a computer or other device. SLP-4AST allows for bi-directional communication between the device and the printer to provide dynamic updating of information stored on the device, allow for real-time monitoring of printer operation, and enable other advanced communication and control functions. The protocol is based on a series of parameters and commands which are transmitted between the two devices, allowing for control and communication with little user interaction. SLP-4AST is capable of transferring data at speeds of up to 9.6 Kbps and is compatible with Windows XP, Windows Vista, Windows 7, and Windows 8 operating systems.
