使用插件或Google扩展程序在Google脚本中打印

Question

I started working on Google Script.

I wonder if there is some way to print in google script( be it text or google sheet data ) when a cell event is generated on the Google sheet.

Any suggestion would be helpful. Thanks.

Answer 1

Google脚本不能使用系统功能，例如打印对话框。

Answer 2

Before proceeding further make sure you have added google cloud supporting printer to google account for printing because of security reasons services like print is not supported by google script

• Open Google Drive.

  1. Right-click to make open Google Sheet.
  2. Add some rows.
  3. Click on Tools menu and select Script editor option.
  4. Select File menu from script editor and then select project properties option.
  5. Note down the Project key (Deprecated) and Script_id from info tab.
  6. Select Resources > Libraries.
  7. Add key MswhXl8fVhTFUH_Q3UOJbXvxhMjh3Sh48 to add library box . Select latest version from list and set identifier OAuth2 .

• Open Google Cloud Console.

  1. To open Google Cloud Console follow this link Google Cloud Console link, there in left navigation section you will find a credentials link.
  2. Click on Credentials link > Create Credentials . A popup will appear. From there select OAuth Client Id option.

  3. Under Application Type select Web Application. Set some name to Application. In authorised script origins url box paste below link. https://apis.google.com

     In authorized redirected url box paste below link. https://script.google.com/macros/d/{SCRIPT_ID}/usercallback

  4. SCRIPT_ID is from project properties.

  5. Save the details.
  6. Note down Client_id and Client_secret for future use.

• Script.

Paste Below code in script window.

function showURL() {
  var cpService = getCloudPrintService();
  if (!cpService.hasAccess()) {
    console.log(cpService.getAuthorizationUrl());
  }
}

function getCloudPrintService() {
  return OAuth2.createService('print')
    .setAuthorizationBaseUrl('https://accounts.google.com/o/oauth2/auth')
    .setTokenUrl('https://accounts.google.com/o/oauth2/token')
    .setClientId('CLIENT_ID’)
    .setClientSecret('CLIENT_SECRET')
    .setCallbackFunction('authCallback')
    .setPropertyStore(PropertiesService.getUserProperties())
    .setScope('https://www.googleapis.com/auth/cloudprint')
    .setParam('login_hint', Session.getActiveUser().getEmail())
    .setParam('access_type', 'offline')
    .setParam('approval_prompt', 'force');
}

function authCallback(request) {
  var isAuthorized = getCloudPrintService().handleCallback(request);
  if (isAuthorized) {
    return HtmlService.createHtmlOutput('You can now use Google Cloud Print from Apps Script.');
  } else {
    return HtmlService.createHtmlOutput('Cloud Print Error: Access Denied');
  }
}

getPrinterList this method will check list of linked printer to account and return printer ID, NAME and DESCRIPTION

function getPrinterList() {
  var response = UrlFetchApp.fetch('https://www.google.com/cloudprint/search', {
    headers: {
      Authorization: 'Bearer ' + getCloudPrintService().getAccessToken()
    },
    muteHttpExceptions: true
  }).getContentText();
  var printers = JSON.parse(response).printers;
  for (var p in printers) {
    Logger.log("%s %s %s", printers[p].id, printers[p].name, printers[p].description);
  }
}

• Last step.

  1. In script window select Select Function from toolbar and select showURL function and run code.
  2. Hit CMD + ENTER to open logs. Copy the url from logs and paste in browser.
  3. Follow the direction and allow permissions for printer.

Run below method with required parameters to add print job to cloud printer.

function printGoogleDocument(docID, printerID, docName) {
  var ticket = {
    version: "1.0",
    print: {
      color: {
        type: "STANDARD_COLOR",
        vendor_id: "Color"
      },
      duplex: {
        type: "NO_DUPLEX"
      }
    }
  };

  var payload = {
    "printerid" : printerID,
    "title"     : docName,
    "content"   : DriveApp.getFileById(docID).getBlob(),
    "contentType": "application/pdf",
    "ticket"    : JSON.stringify(ticket)
  };

  var response = UrlFetchApp.fetch('https://www.google.com/cloudprint/submit', {
    method: "POST",
    payload: payload,
    headers: {
      Authorization: 'Bearer ' + getCloudPrintService().getAccessToken()
    },
    "muteHttpExceptions": true
  });

  response = JSON.parse(response);

  if (response.success) {
    Logger.log("%s", response.message);
  } else {
    Logger.log("Error Code: %s %s", response.errorCode, response.message);
  }
}
