I'm trying to print from multiple (up to two) printers using the request library:
for(var i = 0; i < printers.length; i++) {
var body = {
"printerid": printers[i],
"ticket": JSON.stringify(ticket),
"title": "TEST PRINT",
"content": content,
"contentType": "text/plain"
};
request({
"method": "POST",
"url": googlePrintUrl+"submit",
"headers": {
"Authorization": "OAuth " + googleAccessToken
},
"body": body
}, function (error, res, body){
if (error) {
console.log("There was an error with Google Cloud Print");
console.log(error);
return;
}
console.log("The server responded with:", body);
});
}
I'm getting this error:
Error: Argument error, options.body.

This seems to be an error with the way we are using the request library, not with the api. But I can't figure out exactly what the error is. I've tried many different changes to the request, but none have worked. Thankful for help.
