Technical Requirements

Printer status feedback is retrieved by Simple Network Management Protocol (SNMP) using the Host MIB (RFC 2790) and Printer MIB (RFC 1759) definition.

For performance and stability reasons the printer status request is routed out of the dialog work process to an external RFC Server, the Internet Graphics Service (IGS). Depending on the connection type of the printer,

IGS talks directly to the printer via SNMP or
IGS talks to SAPSprint which in turn talks to the printer by SNMP

For more information about SNMP, visit the homepage of the Internet Engineering Task Force at: http://ietf.org/ and http://tools.ietf.org/.

Prerequisites

Internet Graphics Service Setup

The Internet Graphics Service (IGS) must be set up and the interpreter RspoConnector must be loaded. Run report GRAPHICS_IGS_ADMIN in the central system: Select tab strip Status and check section Registered_Interpreter. The interpreter RSPOCONNECTOR must be listed here.

For more information about IGS Setup, see Configuring the IGS for ABAP-based Front-End Technology. This documentation is available from the SAP Library, following:

For general information about installing and configuring the IGS, see Internet Graphics Service. This documentation is available from the SAP Library, following:

RFC Destination

RFC destination IGS_RFC_DEST is required because the Central System uses it for communication with IGS.

SAPSprint Service Setup

For Access Method S only

Output devices must be connected over a TCP/IP port to their Windows machine. See Setting Up Remote Printing for Microsoft Windows PCs for details.
SAPSprint must be up and running. Protocol version must be 229 or higher. Check the protocol version of SAPSprint with the CLI command 'sapsprint -v':
Syntax
1. ```
C:\Development\fes\dev\src\dbg\ntintel>sapsprint -v
This is SAPSprint Version 7, 1, 0, 0.1, 0, 1, 8 for Windows (32Bit)
Protocol Version 229
Copyright ® 2005 SAP AG
```
End of the code.

When the line stating the protocol version is not displayed, SAPSprint uses version 228 or lower. To find out more about versions and installation instructions, see 894444.
