Hi!
I want to change the color background but in a way that i will print the color olso.
can i do it?
im using autocad 2009

You can type in OP to open your options dialogue box.  Somewhere in there it gives you the option to set your background color.  As for printing, it will only print the way you set your plot style table to be (.ctb file).  The background is never meant to be printed.  Only objects print.
