how to remove print this page button ? �_�

Clicking Edit -> Configuration -> Toolbars will open up the plain text file called toolbars.cfg (each skin has it's own), which contains all of the code that creates and defines the toolbars and buttons.

In it you can change this...

 	Print{
 	ID_FILE_PRINT|Print
 	Print this page. Right-click for more options.
 	toolhot.bmp[6]
 	toolcold.bmp[6]
 	tooldead.bmp[6]
 	}

to this...

#	Print{
#	ID_FILE_PRINT|Print
#	Print this page. Right-click for more options.
#	toolhot.bmp[6]
#	toolcold.bmp[6]
#	tooldead.bmp[6]
#	}

...and the button will be hidden.
