I'm trying to ultimately silently print using Google Cloud Print from a POST function that is called from code on a website. I succeeded in testing cloud printing using my account and my printers using a form submit. (you can see the code that worked for that here: https://stackoverflow.com/questions/23975931/programatically-change-file-name-in-google-chrome-print)
The form submit didn't ask me for any authorization that I could tell. It asked me for xsrf. I stumbled across the answer for this by testing here: https://www.google.com/cloudprint/simulate.html
So my question is can some amazing person please take pity on me and post the entire code for POST to submit a print job to GCP INCLUDING the format for authorization and where I get that info?
I have read the manuals for cloud printing and the info on how to get an oauth (although I don't understand that part yet) I am missing something that will be obvious to people who have done this before.
I have tried the php code at github - although I do not usually code in php.
I have programmed a lot of API's and there is something I am just missing here.
Thank you profusely in advance!
