OSX - 捕捉到打印作业。 [英] OSX - Catch to print jobs.

问题描述

我一直在做我的研究，但我找不到（印有或者有多少页）捕多少打印作业用户发送到打印机的一种方式。

I've been doing my research but I can't find a way of catching how many print jobs a user has sent to the printer (or how many pages have printed).

我想要做的是一个OSX用户打印的页的简单的计数器。你有没有见过这样的事情？

What I want to do is a simple counter of pages printed by a OSX user. Have you seen anything like it?

1：可以通过软件在电脑里，而不是打印机来算多少的打印作业。
2：计数多少页？

1.- Be able to count how many print jobs via software in the computer, not the printer. 2.- Counting how many pages?

推荐答案

OS X使用纸杯印刷。你可以列出完成，但是用户USER_NAME工作：

OS X uses cups for printing. You can list completed jobs for user user_name with:

lpstat -W completed -u user_name

您可以尝试以获得在/ var /日志/杯/页面日志打印的页数，但这个文件的内容取决于打印机驱动程序。从杯文档：

You may try to get the number of pages printed from /var/log/cups/page_log, but the content of this file depends on the printer driver. From cups documentation:

页记录

CUPS记录每一个打印系统的页面日志文件的页面。
  页面日志仅适用于提供网页司机
  会计信息，通常所有的PostScript和CUPS光栅
  设备。原始队列和队列使用第三方解决方案，如
  的Foomatic一般没有有用的网页会计信息
  可用。

CUPS logs every page that is printed on a system to the page_log file. Page logging is only available for drivers that provide page accounting information, typically all PostScript and CUPS raster devices. Raw queues and queues using third-party solutions such as Foomatic generally do not have useful page accounting information available.
