General specifications
LP architecture
An LP session involves at least two programs:
• an LP client program
• an LP server program.
Depending on the specific functional request, the user will normally use different client programs
to communicate with the lpd program. In general, one single lpd program will handle all different
user requests.
The actual names and detailed behaviour (program options) of the LPD client programs depend
on the host Operating System environment. In general, there are Unix BSD style and Unix
System V style systems. For these kinds of systems, the user programs are mostly named as
follows:
User program names in System V Unix and BSD Unix
Functionality requested by the
user System V Unix user program BSD Unix user program
Submit print jobs lp, rlp lpr
Cancel print requests cancel lprm
Display status lpstat lpq
Also the LP server programs often have different names in System V and BSD Unix
environments:
LPD server program names in System V Unix and BSD Unix
System V Unix server pro‐
gram BSD Unix server program
LPD server programs lpsched, lpNet, rlpdaemon lpd
For LP system management and control purposes, the host system normally offers specific
commands for the system administrator. These commands are local to the host system, and are
of no direct need while printing to the imagePRESS C7010VPS series.
