I recently picking up applescript, and wanted to my my printing progress automated.

Basically i would like to print photos that i took from my Canon 40D into a name card size photo paper.

	-- Choose printer to print
	tell application "Printer Setup Utility"
		if current printer is equal to printer printer1 then
			set current printer to printer printer2
			set current printer to printer printer1
		end if
	end tell
	-- Ask PS to print
	tell application "Adobe Photoshop CS3"
