SNA Print Server Data Filter
The Host Print Service feature of Host Integration Server 2000 and SNA Server provides server-based 3270 and 5250 printer emulation, allowing host applications to print to a LAN printer supported by Windows 2000 Server, Windows NT Server, and Novell NetWare. This section introduces the SNA Print Server Data Filter API (sometimes referred to as the Print Exit API) that can be used to extend the capabilities of the Host Print Service in Host Integration Server 2000 and SNA Server. The user can provide a print data filter DLL that will be called by Host Print Service when a print job is initiated, when data is sent to the printer, and when the print job is completed. This print data filter DLL can:
- Send data to the printer when a job starts (print a banner page, for example).
- Perform special processing on the data to be printed.
- Send data to the printer upon print job completion (print a trailer page, for example).
