Hi all
I am trying to change the printer(like paper source ,etc) setting in C#. But i am unable to do it. I am not sure how to do it. should i have to use WIN API like Openprinter , getprinter , setprinter . I did try with PrinterSetting.setHDevMode but it does not work. Its their is a simple way to change printersetting.
thanks

Try using the PageSetupDialog class. I think this has the functionality
that you are looking for.
Hope that helps,

Thanks Marc for reply . I appreciate it
My requirement was to change the printer setting programmatically. I found out the solution . Word API do provide interface to change pagesource of the document (ActiveDocument.PageSetting). But is does not guarantee the duplex property will work.() . We have to do this by using WIN API like setprinter. The problem what I was facing about setprinter is it was not working. At last I re-wrote some portion of the code and IT worked , Following is the C# code for changing the printer setting , again it will not work for network printer . It will throw up access denied error. I am not able to understand why MS office is able to change the network printer propertied but why not C# code using win api
