Google 应用程序脚本 getAs('application/pdf') 布局

Question

我正在使用我在此处找到的应用程序脚本从电子表格生成 PDF 文件。这个使用了很好的旧方法 getAs('application/pdf') 并且效果很好。

问题在于以这种方式生成的 PDF 文档具有不需要的不对称边距（右侧较大，左侧较窄）。我只是想让页面居中。奇怪的是，当我从 Google 菜单 File -> Print（或 Ctrl + P）打印时，文档显示正确居中。

我的代码如下所示：

function CreaPDF() {
  //The function prints an invoice to PDF. First it copies spreadsheet to a new document.
  //Deletes all sheet except the one to print. Saves it to PDF. 
  //It overwrites any existing doc with same name.

  var sourceSpreadsheet = SpreadsheetApp.getActive();          
  var sheetName = "Factura";
  var folderID = getParentFolder(); // Folder id to save in a folder.
  var sourceSheet = sourceSpreadsheet.getSheetByName(sheetName);
  var folder = DriveApp.getFolderById(folderID); 
  var numf = sourceSpreadsheet.getRangeByName("NumeroFactura").getValue();
  var anof = numf.split("/",2);   // Seeks number and year -> filename 

  var pdfName = anof[1] +"_Factura_" + anof[0]+ "_Dra_Salazar"; // Nombre del documento;

  //Copy whole spreadsheet 2 temporary sheet
  var destSpreadsheet = SpreadsheetApp.open(DriveApp.getFileById(sourceSpreadsheet.getId()).makeCopy("tmp_convert_to_pdf", folder))

  //delete redundant sheets
  var sheets = destSpreadsheet.getSheets();
  for (i = 0; i < sheets.length; i++) {
    if (sheets[i].getSheetName() != sheetName){
    destSpreadsheet.deleteSheet(sheets[i]);
    }
  }

  //Deletes pdf if already exists
  var files = DriveApp.getFilesByName(pdfName);
  while (files.hasNext()) {
   files.next().setTrashed(true);
   }
  var destSheet = destSpreadsheet.getSheets()[0];
  //repace cell values with text (to avoid broken references)
  var sourceRange = sourceSheet.getRange(1, 1,sourceSheet.getMaxRows(),sourceSheet.getMaxColumns());

  var sourcevalues = sourceRange.getDisplayValues();
  var destRange = destSheet.getRange(1, 1, destSheet.getMaxRows(), destSheet.getMaxColumns());
  destRange.setValues(sourcevalues);

  SpreadsheetApp.getActiveSpreadsheet().toast('Creando PDF');

  //save to pdf
  var theBlob = destSpreadsheet.getBlob().getAs('application/pdf').setName(pdfName);
  var newFile = folder.createFile(theBlob);

  //Delete the temporary sheet
  DriveApp.getFileById(destSpreadsheet.getId()).setTrashed(true);
  return true;
}

我打印时的设置是：

• 纸张尺寸：“A4”
• 比例：“正常”（我也尝试过：“适合宽度”和“适合页面”）
• 方向：“肖像”
• 边距：“正常”

正如在谷歌帮助论坛中看到的，谷歌打印方式似乎是一个老问题。总之，似乎没有保存打印设置，也无法将任何参数传递给 getAs('application/pdf') 方法。所以我假设该方法（和菜单打印选项）使用无法修改的默认参数。有什么解决办法吗？“打印或更改页面设置”帮助页面没有太大帮助。

非常感谢

试试这个基于https://ctrlq.org/code/19869-email-google-spreadsheets-pdf 的解决方案

使用导出 url 参数，您可以为结果 pdf 设置所需的选项。您还可以设置要导出的工作表的特定 id，因此您不再需要复制整个电子表格。

function CreaPDF() {
  //The function prints an invoice to PDF. First it copies spreadsheet to a new document.
  //Deletes all sheet except the one to print. Saves it to PDF. 
  //It overwrites any existing doc with same name.

  var sourceSpreadsheet = SpreadsheetApp.getActive();          
  var sheetName = "Factura";
  var folderID = getParentFolder(); // Folder id to save in a folder.
  var sourceSheet = sourceSpreadsheet.getSheetByName(sheetName);
  var folder = DriveApp.getFolderById(folderID); 
  var numf = sourceSpreadsheet.getRangeByName("NumeroFactura").getValue();
  var anof = numf.split("/",2);   // Seeks number and year -> filename 

  var pdfName = anof[1] +"_Factura_" + anof[0]+ "_Dra_Salazar"; // Nombre del documento;

  SpreadsheetApp.getActiveSpreadsheet().toast('Creando PDF');

  // export url
  var url = 'https://docs.google.com/spreadsheets/d/'+sourceSpreadsheet.getId()+'/export?exportFormat=pdf&format=pdf' // export as pdf / csv / xls / xlsx
  + '&size=A4'                           // paper size legal / letter / A4
  + '&portrait=true'                     // orientation, false for landscape
  + '&fitw=false'                        // fit to page width, false for actual size
  + '&sheetnames=false&printtitle=false' // hide optional headers and footers
  + '&pagenumbers=false&gridlines=false' // hide page numbers and gridlines
  + '&fzr=false'                         // do not repeat row headers (frozen rows) on each page
  + '&gid='+sourceSheet.getSheetId();    // the sheet's Id

  var token = ScriptApp.getOAuthToken();

  // request export url
  var response = UrlFetchApp.fetch(url, {
    headers: {
      'Authorization': 'Bearer ' +  token
    }
  });

  var theBlob = response.getBlob().setName(pdfName+'.pdf');

  // delete pdf if already exists
  var files = folder.getFilesByName(pdfName);
  while (files.hasNext())
  {
    files.next().setTrashed(true);
  }

  // create pdf
  var newFile = folder.createFile(theBlob);

  return true;
}
