When doPDF convert wordpad document, it always add an extra blank page
to the end of the new pdf docement. How to suppress this extra blank
page? Thank you.
dopdf doesn't add blank pages in wordpad conversion, i just tested this here. most likely you have a blank page in wordpad, so in the wordpad document put your cursor right where the last character of the text finishes, and after that press Ctrl+Delete to make sure you delete all the unnecessary spaces following it. print it again to dopdf after that.
