KashFlow uses HTML to generate your PDF documents. This allows for great flexibility although can result in an anomaly if you’ve got extra spaces in your additional text box, this can result in your documents appearing to shrink to fit on the page. To solve this problem you’ll need to modify your additional text.
Removing Additional Spaces
To solve this problem, navigate to:
Settings > PDF Themes > Select your default theme > Misc Options
Then of the Additional Text field remove the excessive spaces between characters, and replace with a line break as you would in a standard text editor.
