Autostart servers (AUTOSTART)
Specifies whether to start automatically the LPD servers when TCP/IP is started by running the Start TCP/IP (STRTCP) command, or the Start TCP/IP Server (STRTCPSVR) command with SERVER(*AUTOSTART) specified. When LPD is started by running the STRTCPSVR command, and SERVER(*AUTOSTART) is not specified, this parameter is ignored and the number of initial servers defined is started regardless of the value of this parameter.
- *SAME
- The autostart value that was previously set does not change.
- *YES
- Start the number of servers defined in the NBRSVR parameter.
- *NO
- Do not start the number of servers defined in the NBRSVR parameter when the STRTCP command is called.

Number of initial servers (NBRSVR)
Specifies the number of LPD servers to start initially when LPD is started by either the STRTCP command or the STRTCPSVR command. The initial number of servers is 2.
The STRTCP command starts all the servers specified in the CHGLPDA command. The STRTCPSVR command starts only one LPD server, regardless of the number of the servers currently running.
LPD works most efficiently when two or more servers are running. Running only one server works, but no jobs can be received while a current job is running. If a large print job is running, new jobs have to wait before LPD is ready to accept any new LPR requests.
- *SAME
- The number of servers that was previously set does not change.
- *DFT
- The number of servers is set to the default value of 2.
- number-of-servers
- The number of servers requested in this parameter is started the next time the LPD server is started. Valid values range from 1 through 20 servers.
