Can't update printer

[MCecile]

When trying to call this API: (https://docs.microsoft.com/en-us/graph/api/printer-update?view=graph-rest-1.0&tabs=http)

I get back the following response:

{

    "error": {

        "code": "400",

        "message": "One or more of the atributes provided are not supported by the printer.",

        "innerError": {

            "date": "2021-04-19T16:23:32",

            "request-id": "bab5ec38-e37c-4579-8f4e-f7c309f3d9b5",

            "client-request-id": "bab5ec38-e37c-4579-8f4e-f7c309f3d9b5"

        }

    }

}

This is when I send the identical defaults that I received on a GetPrinter call:

{

    "defaults": {

        "copiesPerJob": 1,

        "finishings": [

            "none"

        ],

        "mediaColor": "Unknown",

        "mediaType": "stationery",

        "mediaSize": "North America Letter",

        "pagesPerSheet": 1,

        "orientation": "portrait",

        "outputBin": "auto",

        "inputBin": "auto",

        "documentMimeType": "application/oxps",

        "pdfFitToPage": false,

        "duplexConfiguration": "oneSided",

        "presentationDirection": "clockwiseFromBottomLeft",

        "printColorConfiguration": "color",

        "printQuality": "medium",

        "contentType": "application/oxps",

        "fitPdfToPage": null,

        "multipageLayout": null,

        "colorMode": "color",

        "quality": "medium",

        "duplexMode": "oneSided",

        "dpi": 600,

        "scaling": null

    }

}

I've tried the process of elimination to determine which default it doesn't like, but it seems like there are many that cause this error. I can successfully just set copiesPerJob, orientation, and outputBin, for what its worth.

Can you tell me what defaults are supported at this time?

Thanks

Hi,

The defaults being configured should be present in the capabilities of the printer.
You can get the capabilities of the printer using this API:
GET https://graph.microsoft.com/v1.0/print/printers/{printerId}?$select=id,displayName,capabilities
