Using the PDF Parallel RIP InfoPrint Manager for AIX provides the PDF Parallel RIP to improve the speed of PDF transforms for most color jobs. It divides a PDF input file into separate pages and distributes these pages to several RIPs running in parallel. Then, it combines the resulting AFP data stream into a printable document. If you define two RIPs on the same InfoPrint AIX server for a PDF input file with pages of a uniform complexity, the Parallel PDF RIP client can render this file into AFP in half the time of the standard PDF transform. While the greatest performance improvements occur for jobs printing on the InfoPrint Color 130 Plus printer, you can use the Parallel PDF RIP client on any printers that produce AFP data. Installing the PDF Parallel RIP client The Parallel PDF RIP client (pdfprs) replaces the standard pdf2afp client on your system. The pdfprs component consists of these: v The pdfprs executable in the /usr/lpp/psf/bin directory v The pdf2afp configuration file in the /usr/lpp/psf/ps2afp directory. The Parallel PDF RIP client is best used on an AIX server or servers, which can have from four to 16 processors. We recommend you set up a configuration to allow for system memory use like that displayed in Table 23. Table 23. Processors required to use the Parallel PDF RIP client Processors Allocated Function Performed 1 network traffic, I/O processes, and general system overhead. 1 pdfprs client as defined in "Sample configuration file for the pdfprs client" on page 177. 1 This first RIP transforms PDF into PostScript data. 1 to n Each RIP is likely to use an entire processor to RIP the PDF files. For each additional daemon RIP as defined in "RIP Daemon configuration files" on page 178. The most basic configuration (the pdfprs client and two additional RIPs) requires a minimum of four processors. Make sure that your configuration can support this feature before installing it and submitting jobs through the InfoPrint Manager pdpr print command. You must create the first RIP to transform PDF input data to PostScript data, then use at least a two-RIP configuration on your InfoPrint AIX server to transform the PDF into AFP data. To demonstrate how this support can be expanded by adding RIPs, this example creates a three-RIP configuration, with the first RIP transforming PDF input data into PostScript data. These RIPs still use the PostScript daemon (ps2afpd), just like the standard PDF transform. From an AIX window, complete this procedure: 1. Create a directory for the PDF Parallel RIP client to distinguish it from the standard PDF data stream transform: Chapter 15. Working with transforms 175
