A jobs module manages print jobs, sending them to the filter and backend processes for final conversion and printing, and monitoring the status messages from those processes. [ 21 ] The CUPS scheduler utilizes a configuration module, which parses configuration files, initializes CUPS data structures , and starts and stops the CUPS program.
Similarly, before spooling was added to PC operating systems, word processors were unable to do anything else, including interact with the user, while printing. Spooler or print management software often includes a variety of related features, such as allowing priorities to be assigned to print jobs, notifying users when their documents have ...
Print emails, attachments, and websites. Save a hard copy of important emails, email attachments, and websites by printing them. When you print an email, only the text will show. Attachments, such as pictures or documents, need to be downloaded and printed separately. Print an email
These drivers convert print data from one format (e.g. PS) to a final device-specific format that the printer hardware can process and create a print. These drivers act as the last stage in delivering a print job to the printer. These drivers are more likely to be embedded in printer firmware. Examples of manufacturer specific formats include:
In computer networking, a print server, or printer server, is a type of server that connects printers to client computers over a network. [1] It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle.
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
Pull printing is a printing feature where a user's print job is held on a server (server-based pull printing) or on a user's workstation (serverless pull printing) and released by the user at any printing device (pulled to the printer) which supports this feature. A number of software products [specify] exist that support
PrintNightmare is a critical security vulnerability affecting the Microsoft Windows operating system. [2] [5] The vulnerability occurred within the print spooler service. [6] [7] There were two variants, one permitting remote code execution (CVE-2021-34527), and the other leading to privilege escalation (CVE-2021-1675).
