Form Submit google cloud print - google-apps-script

Question

I could use some help with creating a script when a Google Form is submitted.
Once the form submitted, the script automatically prints a Google Spreadsheet to a Google Cloud-based printer without bringing up the print dialog window.
I've read through Google Cloud Print Info
The idea behind the script is simple:
User fills out form
Form is then submitted
Script updates cells with information user put in
Script then prints to google cloud printer
Shipping label is ready
The below script will print a ticket but how do i add the printer capabilities to the POST request?
The code I have so far:
function onsubmit(e) {
var pid = "123456789"; //place printer id here
var sheetid = "123456789"; //place sheet id here
var ss = SpreadsheetApp.getActiveSpreadsheet();
var info = ss.getSheetByName('Form responses 1');
var lastRow = info.getLastRow();
var sheet = SpreadsheetApp.setActiveSheet(ss.getSheetByName('TICKET'))
authorize();
var url = "https://www.google.com/cloudprint/submit?printerid="+pid+"&contentType=google.spreadsheet&content="+sheetid+"&title=PrintingTicket";
var options = {
method: "post",
oAuthServiceName : "print",
oAuthUseToken : "always"
};
info.hideSheet();
var response = UrlFetchApp.fetch(url, options);
return Utilities.jsonParse(response.getContentText());
}
function authorize() {
var oauthConfig = UrlFetchApp.addOAuthService("print");
var scope = "https://www.googleapis.com/auth/cloudprint";
oauthConfig.setConsumerKey("anonymous");
oauthConfig.setConsumerSecret("anonymous");
oauthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
oauthConfig.setAuthorizationUrl("https://accounts.google.com/OAuthAuthorizeToken");
oauthConfig.setAccessTokenUrl("https://www.google.com/accounts/OAuthGetAccessToken");
}
