Is possible print the pdf from an external button?

Currently, that's not possible using Embed API. printing must be triggered manually. There is no API to make the viewer print.

It's my code

class ViewSDKClient {
  constructor(base64File, clientId, documentId) {
    this.readyPromise = new Promise((resolve) => {
      if (window.AdobeDC) {
        resolve()
      } else {
        document.addEventListener('adobe_dc_view_sdk.ready', () => {
          resolve()
        })
      }
    })
    this.adobeDCView = undefined
    this.base64File = base64File;
    this.clientId = clientId;
    this.documentId = documentId;
  }

  ready() {
    return this.readyPromise
  }

  previewFile(divId, viewerConfig) {
    const config = {
      clientId: this.clientId,
    }
    if (divId) {
      config.divId = divId
    }

    this.adobeDCView = new window.AdobeDC.View(config)

    function base64ToArrayBuffer(base64) {
      var bin = window.atob(base64)
      var len = bin.length
      var uInt8Array = new Uint8Array(len)
      for (var i = 0; i < len; i++) {
        uInt8Array[i] = bin.charCodeAt(i)
      }
      return uInt8Array.buffer;
    }

    const previewFilePromise = this.adobeDCView.previewFile(
      {
        content: { promise: Promise.resolve(base64ToArrayBuffer(this.base64File)) },
        metaData: {fileName: this.documentId+'.pdf'},
      },
      viewerConfig,
    )

    previewFilePromise.then(adobeViewer => {
      adobeViewer.getAPIs().then(apis => {
        debugger
        apis.getPDFMetadata()
        .then(result => console.log(result))
        .catch(error => console.log(error));

        });

    });

    return previewFilePromise
  }

  previewFileUsingFilePromise(divId, filePromise, fileName) {
    this.adobeDCView = new window.AdobeDC.View({
      clientId: this.clientId,
      divId,
    })

    this.adobeDCView.previewFile(
      {
        content: {promise: filePromise,},
        metaData: {fileName: fileName,},
      },
      {},
    )
  }

  registerSaveApiHandler() {
    const saveApiHandler = (metaData, content, options) => {
      console.log(metaData, content, options)
      return new Promise((resolve) => {
        setTimeout(() => {
          const response = {
            code: window.AdobeDC.View.Enum.ApiResponseCode.SUCCESS,
            data: {
              metaData: Object.assign(metaData, {
                updatedAt: new Date().getTime(),
              }),
            },
          }
          resolve(response)
        }, 2000)
      })
    }

    this.adobeDCView.registerCallback(
      window.AdobeDC.View.Enum.CallbackType.SAVE_API,
      saveApiHandler,
      {},
    )
  }

  registerEventsHandler() {
    this.adobeDCView.registerCallback(
      window.AdobeDC.View.Enum.CallbackType.EVENT_LISTENER,
      (event) => {
        console.log(event)
      },
      {
        enablePDFAnalytics: true,
      },
    )
  }
}

export default ViewSDKClient
