推荐答案
作为开发人员和用户，我个人讨厌这种行为(跳过打印对话框).
这是我对MS Word的#1烦恼，谢天谢地，大多数应用程序都没有效仿.
通常，我至少可以访问4台打印机，甚至可以访问更多打印机...以及打印到文件或PDF的功能.
如果我没有机会选择:(a)什么打印机，(b)什么纸张尺寸，(c)什么方向，(d)什么比例，(e)彩色vs.黑白，和(f )什么打印质量，我都很沮丧.
这些是用户选项和首选项.除非您有充分的理由避免使用这些选项，否则请不要删除用户的选择.

基本上，打印对话框是Web浏览器中内置的安全功能.
设想一种情况，您访问Domino的网站订购比萨饼，而无需单击页面上的任何内容，打印机将开始在连接到计算机的打印机上打印比萨饼菜单，直到打印机缺纸.您会满意吗?
因此，除非用户批准打印操作，否则浏览器不允许打印.由于这是浏览器功能，因此您无法覆盖它.
下面的评论中提到的针对您的方案的解决方法是生成一个100页的pdf，一次可打印100页.
As a developer, AND a user, I personally HATE this behavior (skipping the print dialog).
This is my #1 annoyance with MS Word, thank goodness most applications didn''t follow suit.
I typically have access to at least 4, if not more printers... plus the ability to print to a file, or a PDF.
If I don''t get the opportunity to pick: (a) what printer, (b) what paper size, (c) what orientation, (d) what scale, (e) color vs. black & white, and (f) what print quality, I get very upset.
These are user options and preferences. Unless you have a very good reason to avoid uses choosing these options, please do not remove the users choice.

Basically the print dialog is a security feature built into the web browsers.
Imagine a scenario where you visit a Domino''s website to order pizzas and without clicking anything on the page , your printer begins printing the pizza menus on the printer attached to your machine until the printer runs out of paper. Will you be happy with it?
So the browser does not allow to print unless the user approves the print action. Since this is a browser feature , you cannot override it.
The workaround for your scenario mentioned in your comment below is to generate a 100 page pdf for printing 100 pages at a time.
