2.Printer controller overview

The printer controller manages print options, provides the user interface, and runs system management and diagnostic operations on demand. The following is an explanation of tasks that enable the job to be printed:

The printer controller detects which job protocol is being sent.

Print option parameters are stored in the Job Pool Manager (JPM) database, which maintains a database of all jobs. This database contains a reference to the print data on the fixed disk, as well as the print options parameters for the print data. The JPM responds to the printer controller commands for deleting, holding, and prioritizing jobs.

Print data is stored on the printer controller disk for queuing and while printing.

When the printer controller begins processing a job, it sends the print data to the decomposer. The decomposer converts the print data into a bitmap in the resolution appropriate to the printing device.

The decomposer utilizes font data from font files stored on the printer controller disk or font information sent to the printer controller with the print job.

When processed data comes back from the decomposer, the printer controller Device Driver transmits the print data and print option parameters to the printer. Printing is then initiated.

After the job has been printed successfully, the print data file is deleted from the disk. If an error inhibits job completion, the printer controller manages the recovery and completion of the job.

The system can manage the processing of multiple jobs and the printing of another job simultaneously. When you are printing IPDS jobs, the printer controller is able to queue multiple PostScript and PCL jobs at the same time. When you are printing PostScript and PCL jobs, you can send only one IPDS job.

The Xerox 4890 is a high-performance digital printing system designed for large volume printing environments, specifically targeting commercial printers and in-plant print operations. This machine is renowned for its exceptional output quality, speed, and versatility, making it a popular choice for businesses that require reliable and efficient printing solutions.

One of the standout features of the Xerox 4890 is its impressive print speed, capable of producing up to 90 pages per minute (ppm). This rapid output allows organizations to meet tight deadlines and handle large print jobs with ease. Its advanced digital imaging technology ensures that every print job is delivered with exceptional clarity and detail, producing sharp text and vibrant graphics that meet the expectations of even the most discerning clients.

The 4890 utilizes a range of innovative technologies that enhance its functionality and ease of use. One such technology is the Integrated Print Server (IPS), which allows for seamless integration into existing workflows and simplifies the management of print jobs. The IPS is designed to handle various file formats and supports advanced printing features such as variable data printing, which is essential for personalized marketing materials and communications.

Additionally, the Xerox 4890 is compatible with the Network Print Server (NPS), enabling organizations to expand their printing capabilities. The NPS facilitates network connectivity, providing users with easy access to the printer from multiple devices across the office or production floor. This promotes collaboration and streamlines the printing process, making it easier to manage jobs efficiently.

The Xerox 4850 also complements the 4890 by offering similar functionality in a slightly different print format. Both machines are designed with scalability in mind, enabling businesses to expand their printing capabilities as their needs evolve. They support a variety of media types and sizes, allowing for diverse printing applications ranging from brochures to banners.

In summary, the Xerox 4890, along with its complementary models like the 4850, provides a comprehensive solution for organizations seeking high-quality, high-speed printing capabilities. With its advanced features, innovative technologies, and robust performance, it stands out as an ideal choice for businesses aiming to enhance their print production efficiency while delivering exceptional output quality.
