Send_job is the name of the lprng function for sending a job to a remote
print server. If you specifiy

515@172.25.1.122

as printer, it will try to connect to port 515 on 172.25.1.122 (default
port) and then try to spool the job to printer 515, cf

| The rm (remote machine or host) and rp or lp printer printcap options
| are used to specify the remote host and printer to be used. These values
| can be extracted from a printcap entry, or supplied in the following
| manner.
| 
|     If the user program is invoked with -Pxxx argument, then the lp
|     option is assigned the value xxx.
|     
|     If no explicit value is specified and the PRINTER environment
|     variable has value xxx, then the lp option is assigned value xxx.
|     
|     If lp has a value of the form rp@rm or rp@rm%port, then the rp, rm,
|     and lpd_port options are assigned the indicated values.
|     
|     If rm or rp does not have a value, then they are assigned the
|     default_host (usually localhost) and default_printer (usually lp)
|     option values.
|     
|     A connection is made to lpd_port on host rm and the file transfer or
|     command is sent as specified in RFC1179.
