printing over network from PHP app
提问by user160108
I have a set of printers connect over a network with Static IP assigned to each printer.
我有一组打印机通过网络连接，静态 IP 分配给每台打印机。
Now i have a PHP web application running on a linux server which needs to send print jobs, to these printer over the network.
现在我有一个运行在 Linux 服务器上的 PHP Web 应用程序，它需要通过网络将打印作业发送到这些打印机。
Is this possible using lpr or cups and how do i go about it.
这是否可以使用 lpr 或 cups，我该怎么做。

You could use the LPR Printer class from here:
您可以从这里使用 LPR 打印机类：
http://www.phpclasses.org/package/2540-PHP-Abstraction-for-printing-documents.html
http://www.phpclasses.org/package/2540-PHP-Abstraction-for-printing-documents.html
Example:
例子：
<?php
include("PrintSend.php");
include("PrintSendLPR.php");
$lpr = new PrintSendLPR();
$lpr->setHost("10.0.0.17"); //Put your printer IP here
$lpr->setData("C:\wampp2\htdocs\print\test.txt"); //Path to file, OR string to print.
$lpr->printJob("someQueue"); //If your printer has a built-in printserver, it might just accept anything as a queue name.

This question has been asked before. See print to a network printer using PHP
这个问题以前有人问过。请参阅使用 PHP 打印到网络打印机
The answer given that time was exec("lpr -P 'printer' -r 'filename.txt');
那个时候给出的答案是 exec("lpr -P 'printer' -r 'filename.txt');
However, the answer was never accepted so not sure whether the OP found it helpful; it certainly looks like it ought to do the trick, but it's not quite a direct and easy method of doing it from within PHP.
但是，答案从未被接受，因此不确定 OP 是否认为它有帮助；它当然看起来应该可以解决问题，但从 PHP 内部实现它并不是一种直接且简单的方法。
A number of other resources I found were also recommending variations on this approach.
我发现的许多其他资源也推荐了这种方法的变体。
Digging a bit deeper, I see PHP has got a Printer module in PECL. However it's only for Windows, and looks like it's not well maintained. But in case it helps, the link it here: http://www.php.net/manual/en/intro.printer.php
再深入一点，我发现 PHP 在 PECL 中有一个打印机模块。但是，它仅适用于 Windows，并且看起来维护得不好。但如果有帮助，请在此处链接：http: //www.php.net/manual/en/intro.printer.php
I think the answer ultimately is that PHP isn't really designed for this kind of thing, and doesn't have built-in functionality to do it. But since you can shell out to external commands using exec()and similar, it shouldn't be too hard to get it working, albeit not quite ideal.
我认为最终的答案是 PHP 并不是真正为这种事情设计的，并且没有内置的功能来做到这一点。但是，由于您可以使用exec()和 类似的命令来执行外部命令，因此让它工作应该不会太难，尽管不是很理想。

i was also doing research on this...and i think the below written code can help you in handling printer in linux
我也在做这方面的研究……我认为下面写的代码可以帮助你在 linux 中处理打印机
<?php
$printer = "\\Pserver.php.net\printername");
if($ph = printer_open($printer))
{
// Get file contents
$fh = fopen("filename.ext", "rb");
$content = fread($fh, filesize("filename.ext"));
fclose($fh);
// Set print mode to RAW and send PDF to printer
printer_set_option($ph, PRINTER_MODE, "RAW");
printer_write($ph, $content);
printer_close($ph);
}
else "Couldn't connect...";
?>

Try PHP::PRINT::IPP
It worked perfectly for me.
它非常适合我。
Basic Usage
基本用法
<?php
require_once(PrintIPP.php);
$ipp = new PrintIPP();
$ipp->setHost("localhost");
$ipp->setPrinterURI("/printers/epson");
$ipp->setData("./testfiles/test-utf8.txt"); // Path to file.
$ipp->printJob();
?>
