I have a PDF that can only be viewed in IE with Adobe Reader due to the DRM.

Printing is allowed, but as per the instructions, I need to zoom to a specific percentage to properly print the document (using the Current View option in the Print dialog).

When the PDF is read in the browser there is no menu bar and I only know how to zoom using the +/- buttons.

How can I zoom to a specific percentage?

Does a floating bar appear near the bottom (Read Mode)? Perhaps Ctrl+H (toggle Read Mode) will work. – Bob May 23 '12 at 10:42
@Bob Ctrl+H does the trick! Yes, the floating bar was always there, but it only has a +/- for zooming. – Louis May 23 '12 at 10:50
That is odd. Perhaps something this PDF defines. – Bob May 23 '12 at 11:01
I mean, it has the standard bar, but the only zoom controls are the +/-. I was unaware that the Adobe Reader icon toggles Read Mode. – Louis May 23 '12 at 11:11
Honestly, I just stumbled across it one day (it was actually a misclick, and before I knew it was called Read Mode). In the standalone Reader program, it uses a cross within a circle instead. – Bob May 23 '12 at 11:13

You probably have Read Mode enabled. It can be toggled with the keyboard shortcut CtrlH.

In Read Mode you actually get a floating bar near the bottom centre of your screen. You can also click the Reader symbol in the circle to switch back to normal mode:

Aside from PDF defined Read Mode settings, standalone PDFs open in normal view while PDFs opened within a browser open in Read Mode. To open in normal view by default within a browser (aside from PDFs created to always open in Read Mode), in the preferences (Edit > Preferences in the Adobe Reader program):
