[**高分求教**]有关套打的问题~~都进来关注一下,急用!!!!

挺拔的劲松 2006-09-21 08:38:23
功能类似于移动收费回执单的打印.

怎样实现连打,在打完一张后直接打印下一张.就是往单据表格里打印内容,单据是已经有的,只是把内容打印上.

现在能够实现单张打印,在连续打印时,第二张的位置固定不住,怎样控制打印机的跑纸距离.

也就是说现在每张打印都要手动调试单据位置,打印完第一张后,第二张位置就不对了,还需要调,如何解决这个问题.

我以前是用了一堆API(主要是winspool.drv库中的AddForm 函数)实现的添加纸张格式，很麻烦。

现在.NET类库中System.Drawing.Printing命名空间下应该有更简单的方法，你自己可以先查查该空间下的方法。

printDocument.DefaultPageSettings.PaperSize =
new PaperSize("自定义", width, height);
width和height就是你设置的大小。

有些打印机的驱动程序不支持太小的纸，这时就用支持小纸的驱动程序(很多驱动程序都可以混用)

设置纸张大小。
如果纸张大小系统已经有了，设置打印机使用该属性。
如果没有该大小，需要添加该纸大小格式。

用程序和手动操作都可以实现
手动的实现在打印机控制面板中操作。
