Printer Job Language (PJL) printing solutions provide problem handling and status information during the print process by using bidirectional communication between the printer and print server over a single TCP/IP port. PJL printing allows you to share a printer between the iSeries™ and other network users, but since the iSeries keeps communicating with the printer until the iSeries output queue is empty, resource sharing is more limited than with either Simple Network Management Protocol (SNMP) or line printer requester/line printer daemon (LPR/LPD).
PJL printing through an iSeries server requires that the printer and printer adapter or network adapter support Printer Control Language level 5e. Also, the cabling, printer and network adapter or print server must be capable and configured for bidirectional communication.
See Configure PJL printers for a list of requirements and information about how to configure PJL printers.
