Export PDf while iterating over a set of values - google-apps-script

Question

I'm fairly new to the world of aumating sheets with scripts and ma still firmly in the 'cobble other peoples code together' phase of writing scripts.
I have a schedule in Google Sheets that display's different department overviews based on the contents of a cell ('B1'). I'm attempting to iterate a list of values through that cell and in each instance export the resulting sheet to pdf.
So far I've got it working, my next hurdle is getting it to export the pdf in landscape rather than portrait. I can see implementations using url export but I'm not confident enough (read keep breaking everything) to implement that in to the script below.
Any help greatly appreciated!
function PrintPDF(){
var df = DriveApp.getFolderById("folderID");
var arr = new Array();
var files = df.getFiles();
while( files.hasNext() ) {
var f = files.next();
arr.push( [ [ f.getId() ] , [ f.getLastUpdated() ] ] );
}
arr.sort( sortFunction );
function sortFunction( a , b ) {
var aDate = new Date(a[1]);
var bDate = new Date(b[1]);
if ( aDate === bDate ) return 0;
else if ( aDate < bDate ) return 1;
else return -1;
};
for( var i=0 ; i<arr.length ; i++ )
DriveApp.getFileById( arr[i][0] ).setTrashed( true );
//Create array of show codes
var Dss = SpreadsheetApp.getActive().getSheetByName('Value Lists')
var Tss = SpreadsheetApp.getActive().getSheetByName('PrintSheet')
var Shows = Dss.getRange('K3:K11').getValues()
var Count = Shows.length
var Code = Tss.getRange('B1')
Logger.log(Count)
Logger.log(Shows)
for (i=0;i<Count;i++){
Code.setValue(Shows[i])
HideBlankRows ()
const folderName = `foldername`;
var ss =SpreadsheetApp.getActiveSpreadsheet()
var name = "Department - "+ss.getRange('B1').getValue()
Logger.log(name)
DriveApp.getFoldersByName(folderName)
.next()
.createFile(ss
.getBlob()
.getAs(`application/pdf`)
.setName(name)
);
}
Code.setValue('')
}
function HideBlankRows() {
var ss = SpreadsheetApp.getActive();
var sheets = ss.getSheets(); // array of all sheet objects in ss
var numSheets = ss.getNumSheets(); // count of sheets
for(sheet in sheets) {
if(sheets[sheet].getSheetName() == "AA") continue;
//show all the rows
sheets[sheet].showRows(1, sheets[sheet].getMaxRows());
//get data from column A
var data = sheets[sheet].getRange('A:A').getValues();
Logger.log(data)
//iterate over all rows
for(var i=0; i< data.length; i++){
//compare column, if no, then hide row
if(data[i][0] == 'Yes'){
sheets[sheet].hideRows(i+1);
}
}
}
}

Your code looks a bit cryptic to me. I don't understand why do you need the arr array if you nowhere use it. Etc.
But whatever. Suppose the code works fine and all you need is to save a PDF file with landscape orientation. In this case you need to replace these lines in your code:
DriveApp.getFoldersByName(folderName)
.next()
.createFile(ss
.getBlob()
.getAs(`application/pdf`)
.setName(name)
);
With this:
savePDFs(name);
And add at the end of your script the function savePDFs():
function savePDFs(name) {
SpreadsheetApp.flush();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var url = ss.getUrl();
//remove the trailing 'edit' from the url
url = url.replace(/edit$/, '');
//additional parameters for exporting the sheet as a pdf
var url_ext = 'export?exportFormat=pdf&format=pdf' + //export as pdf
//below parameters are optional...
'&size=a4' + //paper size
'&portrait=false' + //orientation, false for landscape, true for portrait
'&fitw=true' + //fit to width, false for actual size
'&sheetnames=false&printtitle=false&pagenumbers=false' + //hide optional headers and footers
'&gridlines=false' + //hide gridlines
'&fzr=false' + //do not repeat row headers (frozen rows) on each page
'&gid=' + sheet.getSheetId(); //the sheet's Id
var token = ScriptApp.getOAuthToken();
var response = UrlFetchApp.fetch(url + url_ext, {
headers: { 'Authorization': 'Bearer ' + token }
});
var blob = response.getBlob().setName(name + '.pdf');
DriveApp.createFile(blob);
}
