The solution was to create a queue (or "spool") of documents to be printed and use a daemon (system process) to manage this queue and send the documents to the printer in the order in which they arrived. Such a system, with an lp command to send documents to the queue, was first introduced in 1973 in Version 4 of Unix. [2]
In Microsoft's command-line interpreter Windows PowerShell, kill is a predefined command alias for the Stop-Process cmdlet. Microsoft Windows XP, Vista and 7 include the command taskkill [5] to terminate processes. The usual syntax for this command is taskkill /im "IMAGENAME".
JaCoCo offers instructions, line and branch coverage. In contrast to Atlassian Clover and OpenClover, which require instrumenting the source code, JaCoCo can instrument Java bytecode using two different approaches: like JCov on the fly while running the code with a Java agent [2] like Cobertura and JCov prior to execution (offline)
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.
The Internet Printing Protocol (IPP) is a specialized communication protocol used between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers). The protocol allows clients to submit one or more print jobs to the network-attached printer or print server, and perform tasks such as querying the status of a ...
The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) is a network printing protocol for submitting print jobs to a remote printer. The original implementation of LPD was in the Berkeley printing system in the BSD UNIX operating system; the LPRng project also supports that protocol.
The embedded firmware of a printer could thus eliminate the need to install any driver on a computer, by accepting print data in a general purpose format (e.g. PDF) via a networking protocol. Despite some efforts to standardize various stages of the printing pipeline, printer interfaces are largely still very proprietary and manufacturer-specific.
Printer Command Language, more commonly referred to as PCL, is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a de facto industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal , matrix , and page printers.
