Editing Print job

{{refimprove|date=July 2007}}
In [[computing]], a '''print job''' is a file or set of files that has been submitted to be printed with a [[Printer (computing)|printer]].

Jobs are typically identified by a unique number, and are assigned to a particular destination, usually a [[Computer printer|printer]]. Jobs can also have options associated with them such as media size, number of copies and priority.

A Print Job is a single queueable print system object that represents a document that needs to be rendered and transferred to a printer. Printer jobs are created on specific print queues and can not be transferred between print queues.

== Components==
Job Id: Uniquely identifies the print job for the given print queue.

Spool file: It is responsible for the on-disk representation of data.

Shadow File: It is responsible for the on-disk representation of the job configuration.

Status: We can describe this in three parts:

* Spooling: It represents the message that the printing application is still working.
* Printing: It represents the message that spool file is being read by the print processor.
* Printed: It represents the message that the job has been fully written to the port.

Data Type: It Identifies the format of the data in the spool file like EMF, RAW.

Other configuration: Name, set of named properties, etc

== Route ==
In larger environments, print jobs may go through a centralized [[print server]], before reaching the printing destination. Some [[Multifunction printer|(multifunction) printers]] have local storage (like a [[hard disk drive]]) to process and queue the jobs before printing.

== Security ==
When getting rid of old printers with local storage, one should keep in mind that confidential print jobs (documents) are potentially still locally [[unencrypted]] on the hard disk drive and can be [[Undeletion|undeleted]].<ref>[https://web.archive.org/web/20100421032430/http://www.cbsnews.com/stories/2010/04/19/eveningnews/main6412439.shtml 'Copy Machines, a Security Risk?' on CBSnews.com (movie)]</ref>
