Import PDF of Current Page in OmniWeb

I like to have PDFs of articles I find online so that can annotate them in Skim. This script imports the current page as a PDF in DTP, providing the option to rename the file and add comments. (To clarify, this for regular web pages, not PDFs that are being viewed in OW–I know that there are scripts on the forum for the latter, but could not find any for the former)

--OW PDF to DTP

-- Options
property destGroup : "/Web PDFs" --Default location
property growlNotif : true --Growl notification
property addTag : true --Add comments on import

tell application "OmniWeb"
	try
		if not (exists browser 1) then error "No browser is open."
		
		-- Setting initial variables
		set theBrowser to front browser
		set theName to the name of theBrowser
		set theURL to the address of theBrowser
		
		if addTag is true then
			set getTags to display dialog ¬
				"Record Name: " & return & theName default answer ¬
				"Enter Comments" buttons {"Rename", "Cancel", "OK"} ¬
				default button "OK" with title "Set Tags"
			
			-- Option to change the proposed name
			if (button returned of getTags) is "Rename" then
				--Titlecase the page name
				set theName to do shell script "python -c \"import sys; print unicode(sys.argv[1], 'utf8').title().encode('utf8')\" " & quoted form of theName
				
				set newName to display dialog ¬
					"New Name:" default answer (theName) ¬
					buttons {"Cancel", "OK"} ¬
					default button 2 with title "Set New Name"
				set theName to text returned of newName
			end if
			
			
			set theComment to text returned of getTags
			if theComment is "Enter Comments" then set theComment to ""
		end if
		
		set theSource to do script "document.documentElement.outerHTML" window browser 1
	end try
end tell
