Supported Access Methods for PAL
A PAL Printer cannot be created without a corresponding output device. What you do in transaction PAL is to put output devices under PAL control which already exist in your system landscape. Afterwards they can only be modified in the Central System where PAL resides.
Each output device you want to use in your PAL landscape must exist in the spool administration (transaction code SPAD) of the Central System or of the Target Systems in order to become available in PAL.
PAL supports output devices with the following access methods:
S (Print on SAPSprint via SAP protocol)
U (Print on LPDHOST via Berkeley protocol)
G (Front-end printing with control technology)
M (E-mail to receiver/owner)
L (Print locally via LP/LPR with signal)
C (Direct operating system call)
E (External output management system)
