Printer protocol refers to the set of actions and commands used in the process of printing a document to a network printer. It involves managing print queues, regulating the transmission of print jobs to the printer, and providing users with information about the job’s status and printer capability. It can also offer flow control in the absence of it from the underlying transport protocol.
The most commonly used protocol for submitting print jobs is LPD, which is a unidirectional protocol. However, there are also more comprehensive bi-directional protocols such as PAP and NDPS that enable printer management and respond to messages and alerts from the printer. The main printing protocols include LPR/LPD Unix standard, Apple’s PAP, Novell’s QMS and NDPS, HP’s JetDirect, and the Internet’s TCP/IP.
What is a print queue?
A print queue refers to the list of pending print jobs waiting to be sent to a printer. Printer protocol manages these queues and regulates the transmission of their contents to the printer.
Can printer protocol offer flow control?
Yes, printer protocol can offer flow control in the absence of it from the underlying transport protocol (UDP, IPX, etc.).
Printer protocol is essential in network printing as it enables the smooth transmission of print jobs from the device to the printer while offering users updates on the job status and the printer’s capability. It also manages and regulates print queues and can offer flow control in some cases. The most commonly used protocols include LPD, PAP, NDPS, JetDirect, and TCP/IP.
Understanding printer protocol is crucial for anyone looking to print on a network printer. By following the standard protocols, users can avoid errors and ensure quick and efficient print jobs. Make sure to check the printer’s manual or manufacturer’s website to determine the appropriate protocol for your use case.
