SDI LPD is a 32-bit print daemon (RFC 1179) that accepts print jobs from a remote computer and prints them on a Windows
local or network printer.
SDI LPD runs on Windows 10 (32-bit and 64-bit), (Windows 8 (32-bit and 64-bit), Server 2012,
7 (32-bit and 64-bit), Vista (32-bit and 64-bit), Server 2008, Server 2003, XP, 2000 and NT.
Any computer operating system that supports LPR (VSE, VM,
z/OS, OS/390, MVS, OS/400 and UNIX) can send print jobs via TCP/IP to SDI LPD.
