I was Introduced to "winspool.drv" not long ago and I was able to use it to change the default printer on windows but can I do more than that like adding or changing the printer setting it self. for example the following pic has a printer that have 3 papers' sizes, can I change the manual feed from 80(72.1)*297 to 80(72.1)*3276. example 1
example two: add new paper size and orientations.
