Choutin.
Thank you for reaching out to support.
Please follow these steps to try and resolve the conflict resulting from the change in server you reported.
Step 1: Create a Backup of the site. *Always good to have a backup ready for manual tasks of removing data or keys as it could cause a website error or crash.
Step 2: Go to the Settings Tab, Click Reset to remove the json secret key. Click Logout of Google Cloud Print account.
Step 3: Navigate to the wp_options.php page for the website, enter in the URL: https://”www.mydomain.com”/wp-admin/options.php, replacing the “www.mydomain.com” with your domain name for the website.
Step 4: Find the field and value for zp_bce0c_491d2, click in the field. Delete the value in the field.
Step 5: Find the field and value for zprint-google-token, click in the field. Delete the value in the field.
Step 6: Scroll to the bottom of the wp_options.php page and click Save Changes.
Step 7: Go back to the Settings Tab, upload the new json secret key from the new migrated domain name and server. Login to Google Account and oAuth. Setup the Location for Printing.
Step 8: Test a new order to verify the print job is starting.
The steps outlined here will remove the old existing key and oAuth data from Google for the previous domain server. After completing these steps, you should be able to successfully setup and migrate to the new domain and print.
