Hi Damian,

In Microsoft Print To PDF Advanced Document Settings, is Paper Size set to Letter as shown in the image below?

Hi Patricia,

Thanks for getting back to me. Yes, Paper Size is set to Letter but the Properties box still shows A4.

The Paper/Output drop down box has lots of size options but there's only a grayed out A4 showing in Properties.

I found a thread with an issue similar to yours. Try out the solution provided by Neil C. Obremski in this thread and check if it helps.

Let us know how it turns out.
