You can import bookmarks into PrintCentral from most browsers on your Mac or PC. Check your browser help file to see how to save your bookmarks. Save your bookmarks as an HTML file inside your WePrint shared files directory.
The location of this directory is in the WePrint settings - "Sharing" tab.

To import the bookmarks into PrintCentral, open the Web Page screen, then tap on the "Bookmarks" button to view and edit your bookmarks.
Select the bookmarks file you just exported and press the "Import" button to complete the import.
