"We were unable to print your label" message when printing a USPS SCAN form in SendPro Online

Issue

The message "We were unable to print your label" appears when printing a USPS SCAN form.

Cause

The USPS SCAN form has expired.

Resolution

USPS SCAN forms are dated and must be printed before 8:00 PM in your time zone. After 8:00 PM, the form for the current date is no longer available. Labels created after 8:00 PM are automatically added to the next day's SCAN form. The next day's SCAN form is available after midnight.

If you did not print today's SCAN form before 8:00 PM, then you will not be able to use a SCAN form for today's shipments. Your individual labels will need to be scanned instead.
