Issue
If you are logged in with a user that does not exist on the sys_user table (for example, maint), trying to use the icon to print to PDF on the homepages will fail.
Symptoms
Clicking the download PDF option results in questions, and then when processing starts, the following error is displayed: "Export failed: An unexpected error has occurred. Please see the instance logs for more details"
The localhost contains the following message: Exit with code 1 due to network error: AuthenticationRequiredError

Reviewing the authentication tokens: https://<instance-name>.service-now.com/oauth_credential_list.do
You can confirm the Authentication token was created correctly for the WebKit HTML to PDF. However, there is no user associated with it.
Cause
OAuth fails to bind to a user (authenticate) if the user does not exist on the sys_user table.
Resolution
Do not use a user that does not exist on the sys_user table to print to PDF from a homepage. (Note that very few users fall into this category.)
Instead, either impersonate another user to print the homepage or use the browser print-to-PDF feature if one is available.
