Chromebook print dialog box disappears when trying to print.

This is an issue that affects the default "Save as PDF" printer and Google Docs (other webpages are printable). Here's how you can fix it.

1. Open a new tab and go to another website (not a Google Doc or Google Drive. Choose an outside website).
2. Try to print the new webpage (CTRL + P). You will notice that the print dialog box will not disappear.
3. Click the "Change" button and choose another printer.  
4. Go back to a Google Doc and try printing again. The print dialog box should now be fixed.

If you continue to have issues, please submit a Web Help Desk ticket.
