How to Print sheet/range using .gs script in Google Sheets? - google-sheets

Question

I am trying to create a script in Google Sheets that select a range and print it. I am trying to print some information based on some parameters. I have the following script that sets the desired range, but I do not see a way to print it using script.
function printInvoice() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var range = sheet.getRange("A1:H46");
range.activate();
}
Any suggestions? Thanks!

Answer 1

You can use the following script:
var PRINT_OPTIONS = {
'size': 7, // paper size. 0=letter, 1=tabloid, 2=Legal, 3=statement, 4=executive, 5=folio, 6=A3, 7=A4, 8=A5, 9=B4, 10=B
'fzr': false, // repeat row headers
'portrait': true, // false=landscape
'fitw': true, // fit window or actual size
'gridlines': false, // show gridlines
'printtitle': false,
'sheetnames': false,
'pagenum': 'UNDEFINED', // CENTER = show page numbers / UNDEFINED = do not show
'attachment': false
}
var PDF_OPTS = objectToQueryString(PRINT_OPTIONS);
function onOpen(e) {
SpreadsheetApp.getUi().createMenu('Print...').addItem('Print selected range', 'printSelectedRange').addToUi();
}
function printSelectedRange() {
SpreadsheetApp.flush();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var range = sheet.getActiveRange();
var gid = sheet.getSheetId();
var printRange = objectToQueryString({
'c1': range.getColumn() - 1,
'r1': range.getRow() - 1,
'c2': range.getColumn() + range.getWidth() - 1,
'r2': range.getRow() + range.getHeight() - 1
});
var url = ss.getUrl().replace(/edit$/, '') + 'export?format=pdf' + PDF_OPTS + printRange + "&gid=" + gid;
var htmlTemplate = HtmlService.createTemplateFromFile('js');
htmlTemplate.url = url;
SpreadsheetApp.getUi().showModalDialog(htmlTemplate.evaluate().setHeight(10).setWidth(100), 'Print range');
}
function objectToQueryString(obj) {
return Object.keys(obj).map(function(key) {
return Utilities.formatString('&%s=%s', key, obj[key]);
}).join('');
}
You will also need to create an html file in your project (File>New>HTML File) with the name js, and paste in the following code:
<script>
window.open('<?=url?>', '_blank', 'width=800, height=600');
google.script.host.close();
</script>
This will create a button in your Sheets menu that will open a PDF with the selected range. You can modify some settings such as the print orientation, its size, or whether to show the gridlines or not on top of the script. If you still want to automatically print the ranges without having to manually go through the print dialog, you can either:
Send the document to your printer using GmailApp API class, if your printer supports such functionality.
Use Google Cloud Print. The following blog post may help you with that: https://ctrlq.org/code/20061-google-cloud-print-with-apps-script

I stumbled on your code quite by chance from an "unallowed question to stack overflow which actually seems to be exactly what I want - could not get any detail on how to print from App Script for sheets.
I have been trying it out but it falls over at the line in your sample
"var htmlTemplate = HtmlService.createTemplateFromFile('js');"
where the service cannot find 'js'. Afraid I do not understand what an html template is anyway - are you able to explain?
