first one, I need to know how control dot matrix prnter.

scenario : click button -> automatically print the data from database

ourold version(VB) is make .dat file -> call system command like this

"ProcessStartInfo("cmd.exe", "/C " + "copy c:\\page.dat LPT1:")

I tried to follow that kind way but it was difficult to make printable format file...

does anyone know how to handle dot matrix printer?

second one,
