I have tried printing an Amazon Direct Fulfillment shipping label and am seeing an error returned:
There has been an issue with retrieving the status of the label generation from Amazon. Please try printing again in a few moments.
This error might appear when Amazon cannot finish processing the transaction during the printing request. When you see this error, please wait 1-2 minutes and try to print the label once more. If the label can not be printed after several minutes still, please contact Technical Support team.
