PHP打印代码（打印到纸上）

Question

Is there a PHP function to print something from a web page (inside the browser)?

I was searching in Google but the result is the print() function. Or any ideas, or any web programming language that you can share. I need a code to print a list of subjects from my database. Sorry for this stupid question. I don't know if that is possible.

Answer 1

If you are talking about a web application, you can bring up the print dialog box with JavaScript using the window.print() function.

Without using activex or other such trickery, there is no way to automatically send something to the printer.

This is a good thing, imagine a malicious web site printing thousands of pages on your machine without your consent.

If you are running a command line php that will depend on the operating system.

Answer 2

尝试此操作，您需要添加php_printer.dll，然后启用该扩展名（在重新启动apache之后） http://in2.php.net/manual/en/function.printer-write.php

Answer 3

It's a little but unclear what you mean? You can use a SQL query to get information from a database, and then use echo to print it out. Is that what you mean?

Answer 4

If the intention is a print preview, where the user can click an “Print this” button and the server will print the document you can use CUPS if you use a Linux/Apple/BSD server. http://www.cups.org/articles.php?L545+TNews+Q
