After customizing my report and adjusting column widths, why does it print out with excessive white space in some columns and wraps the entries in others?

Welcome to the Community, Elizabirdy.

Let me share some insights about customizing and printing reports in QuickBooks Online. 

We need to make sure to display all pages and reports properly, here are the requirements in QuickBooks Online:

• Screen resolution set to 1024x768 or higher
• Dots-per-inch (DPI) set to "Normal" or "100%"
  Note: We recommend that you maximize the browser window for working in QuickBooks Online, particularly if your resolution is 1024x768.

Then, you can adjust the column widths by clicking and dragging the column dividers located at the top of your report.

If you are still getting an error, you can start by either logging into QBO using an incognito browsing session, using a different browser, or deleting your browsing history. Just use these keyboard shortcuts to open a private or incognito browsing session:

• Ctrl + Shift + N  for Google Chrome
• Ctrl + Shift + P  for Firefox
• Control + Option +P if you're using Safari

Once done, log back in and resize the column in your transaction report. You can also delete cache and other temporary internet files.
