Selecting the IPP 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 IPP (Internet Printing Protocol) protocol if you want IP PrintWay to transmit data sets over the Internet to the printer. When you select the IPP protocol, an IPP server must be running in the remote printer or host system.

IP PrintWay transmits the print data stream to the IPP server at the URL that you specify in the printer definition. A job submitter cannot override the URL when submitting a print job. This means that you must create one printer definition for each printer.

Along with the data, IP PrintWay also transmits a control file containing these IPP job attributes:

• copies
• document-name
• job-name
• requesting-user-name
• sides

The IPP server running in the printer or print server processes the IPP job attributes that IP PrintWay sends with each print request. The IPP server ignores any IPP job attributes that it does not support. For example, some IPP servers do not support the copies and sides attributes, so the output might not print as requested. If the IPP server ignores one or more of the IPP job attributes for a print job, a message in the IP PrintWay message log indicates which job attributes were ignored.

Limitations: When you select the IPP protocol, IP PrintWay does not support:

• Concatenate job option of the Dataset grouping field
• Automatic dataset grouping field

Related customization tasks: These IP PrintWay customization tasks are related to the IPP protocol. For information about how to do these tasks and other customization tasks related to the IPP protocol, see z/OS Infoprint Server Customization.

• If you did not install Infoprint Server files in default directories, specify the directories in the STDENV data set in the IP PrintWay startup procedure.
• Customize the TCP/IP component of z/OS Communications Server.
• When more than one copy is requested, IP PrintWay extended mode writes temporary files to the /var/Printsrv/printway directory. If necessary, increase the amount of space available to this directory.
• When you specify a value in the Maximum document size field or select the Delete form feed option, IP PrintWay basic mode writes temporary files to hiperspace. If necessary, increase the amount of available hiperspace in the IP PrintWay FSS definition.
