推荐答案

没有人可以给您正确的答案.

您尚未指定打印方式，使用的报告类型(如果有的话).


一般来说:
您将必须创建/保存2个对象，即打印设置和页面设置.
(都在system.drawing.printing命名空间中)
为了保存它们，我建议您将它们序列化为文本文件，可以将其保存到数据库中，但是我发现某些打印机有些麻烦.

然后将这些对象应用于您的报告.当然，您的报告必须经过精心制作，才能以正确的纸张尺寸显示所有数据.

一些打印机会自动缩放那里的页面，但是我不知道有任何这样做的矩阵打印机.

您还可以只在屏幕上显示报告，然后让用户单击打印"按钮(通常，报告生成器可以在屏幕上显示该报告，并且应该在其中显示打印"按钮)，然后用户便可以选择打印机.但这意味着用户必须每次都执行此操作.

Nobody can give you a correct answer to this.

You haven''t specified how you do your printing, what kind of report do you use (if any at all).


Generally speaking:
You''ll have to create / save 2 objects, a printsettings and a pagesettings.
(both in the system.drawing.printing namespace)
For saving them I suggest you serialize them into text files, you could do it to a database but I''v found that to be somewhat troubling with some printers.

Then apply those objects to your report. Of course your report will have to be made such that it can display all data with the correct papersize.

Some printers scale there pages automatically but I don''t know of any matrix printers that do this.

You can also just display your report on the screen and then let the user click the print button (normally your report generator has a way to display it on screen and that print button should be in it) and from there the user will be able to select the printer. But that means the user has to do this every time then.
