摘要:
Embodiments herein describe a two-phase printing process that utilizes page-to-resource tracking during the first rip-to-spool phase in order to perform resource scheduling during the second print-from-spool phase. In one embodiment, compute nodes include a RIP and a raster builder. A controller receives a print job, identifies a distribution of logical pages in the print job to the compute nodes, and generates page assignment information that maps the logical pages to the compute nodes based on the distribution. The compute nodes rasterize the logical pages to generate intermediate data using the RIPs, and store the intermediate raster data at a RIP spool. The controller directs a distribution of the intermediate raster data from the RIP spool to the compute nodes based on the page assignment information, and the compute nodes assemble the intermediate raster data into complete raster data using the raster builders.
