CUPS allows printer manufacturers and printer-driver developers to create drivers more easily that work natively on the print server. Processing occurs on the server, allowing for easier network-based printing than with other Unix printing systems.
Gutenprint (formerly Gimp-Print) is a collection of free-software printer drivers for use with UNIX spooling systems, such as CUPS, LPR, and LPRng. These drivers provide printing services for Unix-like systems (including Linux and macOS ), RISC OS and Haiku .
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.
cancel previously submitted jobs IPP uses TCP with port 631 as its well-known port . Products using the Internet Printing Protocol include Universal Print from Microsoft, [ 23 ] CUPS (which is part of Apple macOS and many BSD and Linux distributions and is the reference implementation for most versions of IPP [ 24 ] ), Novell iPrint , and ...
A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer. Printer drivers are typically implemented as filters . They are usually named the front end of the printing system, while the printer spoolers constitute the back end .
Note that the LPD queue name is case sensitive. Some modern implementations of LPD on network printers might ignore the case or queue name altogether and send all jobs to the same printer. Others have the option to automatically create a new queue when a print job with a new queue name is received. This helps to simplify the setup of the LPD ...
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 PPD also contains the PostScript code (commands) used to invoke features for the print job. As such, PPDs function as drivers for all PostScript printers, by providing a unified interface for the printer's capabilities and features. For example, a generic PPD file for all models of HP Color LaserJet contains:
