please read this: not sure if this is the answer of your question:
I was unable to or forgot to print my application when I got to the end of the application process.?
Answer:
Depending on how you have configured your computer you may get an error when you try to print. To recover a completed application select the Existing Applicants Login link on the left menu. You will be asked to enter your Application Security details and your unique visa application number. Your application number was included in the email we sent you when you completed your visa application. When you successfully login, you will have the option to print your application again. Note: that you are not permitted to edit your application once it has been submitted.
