I have just gone through this process, and was approved at the embassy so when it comes to the I-134 what we did is i had my fiance go through the form on the PDF on the computer where you can enter the details digitally before printing (There are a few areas which can not be entered online) Then once printed off just fill in what else is required yourself. Then she went to a UPS Store and ask them to photocopy the I-134 and send them via email to me which i then printed off and took to the embassy for my interview.
