Upload documents using the Microsoft Graph Universal Print API

To print a document using the Universal Print API in Microsoft Graph, you create a print job, upload a document, and then start the print job. This article describes how to upload a document, which starts with creating an upload session.

To upload a file, or a portion of a file, your app makes a PUT request to the uploadUrl value received in the createUploadSession response. You can upload the entire file, or split the file into multiple byte ranges, as long as the maximum bytes in any given request is less than 10 MB.

The segments of the file can be uploaded in any order and can be uploaded in parallel, with up to four concurrent requests. When all the binary segments of a document are uploaded, the binary file is linked to the printDocument.

Note: If your app splits a file into multiple byte ranges, we recommend that the size of each byte range is a multiple of 200 KB unless you're using the Microsoft Graph SDK, which requires the segment size to be a multiple of 320 KB.

Upload a file

Request

Make a PUT request to the uploadUrl value received in the createUploadSession response.

Request headers

Name Description
Content-Range bytes {startByteIndex}-{endByteIndex}‬/{documentSizeInBytes}. Required.
Content-Length {contentLength}‬ Required.

Request body

The request body is a binary blob containing the bytes of the document that are specified as an inclusive byte range in the Content-Range header.

Example

PUT https://print.print.microsoft.com/uploadSessions/5400be13-5a4e-4c20-be70-90c85bfe5d6e?tempauthtoken={token}
Content-Range: bytes=0-72796/4533322
Content-Length: 72797

<bytes 0-72796 of the file>

Here, 0 and 72796 are the start and end indexes of the file segment and 4533322 is the size of document.

Response

When the request is complete, the server will respond with 202 Accepted if there are more byte ranges that need to be uploaded.

HTTP/1.1 202 Accepted
Content-Type: application/json

{
  "expirationDateTime": "2020-10-25T02:19:38.1694207Z",
  "nextExpectedRanges": ["72797-4533321"]
}

Your app can use the nextExpectedRanges value to determine where to start the next byte range. You might see multiple ranges specified, indicating parts of the file that the server has not yet received. The nextExpectedRanges property indicates ranges of the file that have not been received and not a pattern for how your app should upload the file.

HTTP/1.1 202 Accepted
Content-Type: application/json

{
  "expirationDateTime": "2020-10-25T02:19:38.1694207Z",
  "nextExpectedRanges": [
  "72797-72897",
  "78929-4533322"
  ]
}

Remarks

  • On failures, when the client sends a fragment the server has already received, the server will respond with HTTP 416 Requested Range Not Satisfiable. You can request upload status to get a more detailed list of missing ranges.
  • Including the Authorization header when making the PUT call might result in an HTTP 401 Unauthorized response. The Authorization header and bearer token should only be sent when creating the upload session. It should be not be included when uploading data to the upload session.

Complete a file upload

When the last byte range of a file is received, the server will respond with an HTTP 201 Created. The response body will also include the property set for the associated printDocument.

Request

PUT https://print.print.microsoft.com/uploadSessions/5400be13-5a4e-4c20-be70-90c85bfe5d6e?tempauthtoken={token}
Content-Length: 10
Content-Range: bytes 4533312-4533321/4533322

<final bytes of the file>

Response

HTTP/1.1 201 Created
Content-Type: application/json

{
   "id": "9001bcd9-e36a-4f51-bfc6-140c3ad7f9f7",
   "documentName": "TestFile.pdf",
   "contentType": "application/pdf", 
   "size": 4533322
}

Note: The upload session is deleted after the document upload is complete.

Get the upload session

To get the upload session, send a GET request to the upload URL.

Request

GET https://print.print.microsoft.com/uploadSessions/5400be13-5a4e-4c20-be70-90c85bfe5d6e?tempauthtoken={token}

Response

HTTP/1.1 200 OK
Content-Type: application/json

{
  "expirationDateTime": "2020-10-25T02:19:38.1694207Z",
  "nextExpectedRanges": [
  "72797-72897",
  "78929-4533322"
  ]
}

Code examples: Create upload session and upload documents


            GraphServiceClient graphClient = new GraphServiceClient( authProvider );

            var properties = new PrintDocumentUploadProperties
            {
	            DocumentName = "TestFile.pdf",
	            ContentType = "application/pdf",
	            Size = 4533322
            };

            var uploadSession = await graphClient.Print.Printers["{printer-id}"].Jobs["{printJob-id}"].Documents["{printDocument-id}"]
            	.CreateUploadSession(properties)
	            .Request()
	            .PostAsync()

            // if using Graph SDK, maxSliceSize should in multiples of 320 KiB
            int maxSliceSize = 320 * 1024;
            var fileUploadTask =
                new LargeFileUploadTask<PrintDocument>(uploadSession, fileStream, maxSliceSize);

            // Create a callback that is invoked after each slice is uploaded
            IProgress<long> progress = new Progress<long>(prog =>
            {
                Console.WriteLine($"Uploaded {prog} bytes of {fileStream.Length} bytes");
            });

            // Upload the file

            var uploadResult = await fileUploadTask.UploadAsync(progress);

Cancel the upload session

To cancel an upload session, send a DELETE request to the upload URL. This should be used in scenarios where the upload is aborted; for example, if the user cancels the transfer.

Temporary files and their accompanying upload session are automatically cleaned up after the expirationDateTime has passed.

Request

DELETE https://print.print.microsoft.com/uploadSessions/5400be13-5a4e-4c20-be70-90c85bfe5d6e?tempauthtoken={token}

Response

HTTP/1.1 204 No Content
