How to Configure DLC/LLC printing for Windows NT
DLC is a simple protocol that is included in Windows NT as standard. It can be used
on other operating systems (such as Windows 3.x) with the addition of vendor
supplied software that supports the Hewlett-Packard JetDirect card. If you are going
to use the TCP/IP protocol for printing, refer to the chapter "How to Configure
TCP/IP printing for Windows NT, LAN Server and OS/2 Warp Server"
✒ Note
Because DLC is a non-routable protocol, there cannot be a router between the print
server and the sending computer.
