Selecting the LPR protocol

In an IP PrintWay™ printer definition, you can select the transmission protocol that IP PrintWay uses to transmit output data sets from the JES spool to the printer, print server, or email destination. IP PrintWay supports these transmission protocols: LPR, direct sockets, IPP, VTAM®, and email.

Select the IP PrintWay LPR protocol if you want IP PrintWay to transmit data sets to the printer or print server using the TCP/IP LPR protocol defined by RFC 1179. When IP PrintWay uses this protocol, an LPD that adheres to RFC 1179 must be running in the remote printer or print server.

When you select the LPR protocol, IP PrintWay transmits data to the LPD at the host name or IP address and print queue name that you specify in the printer definition. A job submitter can override the IP address and print queue name specified in the printer definition by specifying the host name or IP address on the OUTPUT JCL statement or in an Infoprint Server job attribute.

Because some job submitters can specify the printer's host name or IP address, you can create one printer definition for several printers that share the same attributes. To use this printer definition, the job submitter must specify the name of the printer definition, the printer's host name or IP address, and the printer's print queue name on the OUTPUT JCL statement or in Infoprint Server job attributes. If the job submitter does not specify the name of the printer definition on an OUTPUT JCL statement, IP PrintWay uses printer attributes specified in the default IP PrintWay printer definition described in Creating an IP PrintWay default printer definition. For more information about job submission, see z/OS Infoprint Server User’s Guide.

When you select the LPR protocol, IP PrintWay also transmits a control file for each data set to the LPD. In the printer definition, you can specify whether you want IP PrintWay to transmit the control file before or after the data set. IP PrintWay converts some attributes that you specify in the printer definition to control codes in this control file. In addition, in the printer definition, you can specify any other control codes that the LPD accepts.

By default, IP PrintWay prints multiple copies of a data set by transmitting the data set to the printer multiple times. Some LPDs, however, can print multiple copies when IP PrintWay transmits the data set to the printer only one time. If your printer supports printing multiple copies of the same data set, you can select the Optimize copies option in the printer definition to improve performance. To determine if your printer supports printing multiple copies of the same data set, select the Optimize copies field and submit a print request with multiple copies. If your printer prints only one copy, deselect this option.

• Customize the TCP/IP component of z/OS Communications Server.
• IP PrintWay extended mode writes temporary data sets to the /var/Printsrv/printway directory. If necessary, increase the amount of space available to this directory.
• IP PrintWay basic mode writes temporary files to hiperspace. If necessary, increase the amount of available hiperspace in the IP PrintWay FSS definition.
