Notepad.exe Command Line Arguments
Action: Print
	%SystemRoot%\system32\NOTEPAD.EXE /p "%1"

Action: PrintTo
	%SystemRoot%\system32\notepad.exe /pt "%1" "%2" "%3" "%4"

Where the arguments are as follows
	%1: filename to print
	%2: printer name
	%3: driver name: "WINSPOOL" <- standard default
	%4: port name: "NE01:" <- standard default

I had a problem using the Windows XP command line utitility "print" to print a text file to a HP Deskjet 3940

	print /d:localprintername filename
	print /d:LPT2 filename
	print /d:\\server\printer filename

All failed when trying to print to the DJ3940

So the following command worked

%SystemRoot%\system32\notepad.exe /pt "%ALLUSERSPROFILE%\Desktop\onsiteList.txt" "\\apf-ma-wb02\HPDJ3940_WB"
rem "\\apf-ma-dc01\maHPLJ3380_R"
