  1. IPPD How workflow techniques can by implemented using IPPD Simon Jones 14th September 2006 IBM Printing Systems jones13@uk.ibm.com

  2. Workflow? • Management and control of a manufacturing process. • Real time interaction with components and products • Division of a complex process into smaller parts or units of work. • Optimisation and automation of activities.

  3. How IPPD Implements Workflow Techniques • Divides the manufacturing process into major phases • Receive • Prepare • Print • Complete • And others in the future, such as Insert, Reconcile, etc. • Each phase consists of one or more steps • Steps are sequential in a phase. • A job passes through a step and is processed by it. • Properties of the job configure the actions of the step. • Jobs can be queued to a step, waiting for it to become available. • Jobs can experience an error condition in a step.

  4. Object Properties • Jobs and devices have properties • Their behaviour is configured by properties in various parts of the workflow. • Properties may be examined and altered through the IPPD • Devices are given properties by a user when they are created. • Jobs are given properties by • A profile, called a JobType • From an attributes file at input, sometimes referred to as a job ticket. • Through evaluation of a set of rules or dependencies.

  5. Receive Phase • Concerned with creating jobs from input files • Single input file – Single job. • Input file group – Parent and child jobs. • Determines the job type to apply, set by • Hot Folder. • Input file name element. • Rules applied to property values received in a job ticket. • Copies the job properties stored in the JobType to the job

  6. Prepare Phase • Preparation of the job ready for output processing • Printing • Email/web • Content Manager • Datastream conversion for printing • Line data • PDF/Postscript • PCL • TIFF, JPEG, etc • Document re-engineering • Value add manipulation of the document content. • Addition or adjustment of factory readable data.

  7. Print Phase • Pre-processing • Build relationship between pages and sheets. • Work out which pages (and sheets) to print. • Scheduling • The “Print Queue” is a pool of jobs from which printers collect and process jobs when they can. • Allocation of jobs to printers is based on scheduling properties. • A subset of jobs that can be scheduled to a particular device can be seen on the GUI. • Printing • Sending data and resources to the printer. • Managing progress and errors. • Streaming multiple jobs to keep the printer at rated speed.

  8. Extending IPPD • IPPD is • Highly configurable. • May contain generic and customised bespoke components that take advantage of a rich set of APIs. • Embodies the philosophy “Fit the product to your business”. • New steps can be added • Any server executable program may be run as a step. • The program can be supplied with job property values. • The program can create files that become job. • IBM will enhance IPPD both through new base functionality product and value add modules • SLA • Visual Workbench • Reports
