How to Change a Typewriter Font in Adobe Acrobat
Adobe Acrobat is the primary software used to create and edit Portable Document Format (PDF) documents. To type new text on a PDF page, or to create a PDF form for others to fill out on their computers, use Acrobat's Typewriter tool.
The tool is helpful for filling out flat forms (non-interactive), as you can simply type over the blank fields. The Typewriter toolbar allows you to change text properties, including the font, font size, colour and line spacing.
Open either a blank page or existing PDF document in Adobe Acrobat.
Click the "Tools" menu.
Select "Typewriter" and then "Show Typewriter Toolbar." The toolbar will appear on-screen.
Select the "Typewriter" tool from the toolbar.
Click an area on the page where you want to begin typing. Type some text.
Click and drag to select the text.
Select a new font from the typeface drop-down menu in the toolbar. The selected text will change to the new font you've chosen.
