问题描述:
我用的是HP6L激光打印机(已设置成默认打印机),HP6L打印机最大能支持A4纸,
可我用的DATAREPORT 页面是A3的,下面的API代码只能
改变A4纸的方响,用下面的代码改成A3纸大小后DATAREPORT提示"纸张宽度
小于DATAREPORT的宽度" 无法显示DATAREPORT。
所以我在打印机里面添加了一个EPSON LQ1600K打印机,
显示A3 大小页面的DATAREPORT时先把LQ1600K设置成默认打印机。
这样用起来非常麻烦。
请问:
1,能用代码来设置HP6L打印机的纸为A3 显示页面大小为A3 的DATAREPORT吗?
"请详细说明和写出详细的代码"
2,或能用代码来改变默认打印机使不同打印机随时设置为默认打印机吗?
"请详细说明和写出详细的代码"
3,或别的什么好的解决办法?

取得打印机:
If Printers.Count < 1 Then
MsgBox "系统没有安装打印机!", vbCritical, App.Title
Unload Me
Exit Sub
End IfDim Prns As Printer
For Each Prns In Printers
List1.AddItem Prns.DeviceName
Next
List1.ListIndex = 0设定默认打印机:
Set Printer = Printers(List1.ListIndex)
只想说一句,用HP6L打印机时,即使你能用代码设成A3大小,实际也不能打印呀,为什么要这样呢?
我设A3大小的纸不是为了打印,
而是为了显示A3 大小的 DATAREPORT。
请问能不能设置默认打印机时直接给打印机名?
不用INDEX号?
我试过了。
无法把EPSON LQ1600K打印机设置成默认打印机。
也无法显示A3大小的DATAREPORT。
认能帮帮我,
这个难度这么大吗?
Printers是一个所有打印机的集合Set Printer = Printers(Index) '你只需要改index值就可以改变打印机详细用法你可以看MSDN
http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q167735你看了就知道了!
我试过改变
Set Printer = Printers(Index)
里的值,可是不关用。
要什么钱?
