Printing does not respond

my console:

Create Job Response: {'version': (2, 0), 'status-code': 0, 'request-id': 24470, 'operation-attributes': {'attributes-charset': 'utf-8', 'attributes-natural-language': 'en'}, 'unsupported-attributes': [], 'jobs': [{'job-uri': 'ipp://192.168.1.92/ipp/print/job-0008', 'job-id': 8, 'job-state': <IppJobState.PENDING: 3>, 'job-state-reasons': 'job-data-insufficient', 'job-state-message': ''}], 'printers': [], 'data': b''}
Created job with ID: 8
Send Document Response: {'version': (2, 0), 'status-code': 0, 'request-id': 65154, 'operation-attributes': {'attributes-charset': 'utf-8', 'attributes-natural-language': 'en'}, 'unsupported-attributes': [], 'jobs': [{'job-uri': 'ipp://192.168.1.92/ipp/print/job-0008', 'job-id': 8, 'job-state': <IppJobState.PROCESSING: 5>, 'job-state-reasons': 'none', 'job-state-message': ''}], 'printers': [], 'data': b''}

But the printer is completely unresponsive

get jobs result:

{'version': (2, 0), 'status-code': 0, 'request-id': 38639, 'operation-attributes': {'attributes-charset': 'utf-8', 'attributes-natural-language': 'en'}, 'unsupported-attributes': [], 'jobs': [], 'printers': [], 'data': b''}
