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.
A server for the LPD protocol listens for requests on TCP port 515. [1] A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character. An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue ...
[10] [11] [12] It can be optionally installed on computers and smartphones with full administrative permissions, if the user chooses to do so. [24] This provides the host user with full access to the guest computer over the Internet, and, like all remote desktop applications, is a severe security risk if connected to an untrusted host.
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1]
The Windows Remote Desktop Connection client can be used to connect to such a server. There is also Azure Virtual Desktop which makes use of RDP and is a part of the Microsoft Azure platform. There is also a VirtualBox Remote Display Protocol (VRDP) used in the VirtualBox virtual machine implementation by Oracle . [ 43 ]
AirPrint is a feature in Apple Inc.'s macOS and iOS operating systems for printing without installing printer-specific drivers.. Connection is via a local area network (often via Wi-Fi), [1] [2] either directly to AirPrint-compatible printers, or to non-compatible shared printers by way of a computer running Microsoft Windows, Linux, [3] or macOS.
Apple has made the source code of the Bonjour multicast DNS responder, the core component of service discovery, available as a Darwin open source project. The project provides source code to build the responder daemon for a wide range of platforms, including Mac OS 9 , macOS , Linux , *BSD , Solaris , VxWorks , and Windows .
Additionally, data conversion was performed on individual workstations rather than a central server. 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.
