Create a Google Apps Script

I need the following. A gmail account where I can send emails, and these emails will automatically be printed to a Google Cloud Printer I will provide access to. The printing should happen within minutes after the gmail account receives the email. The email containing the attachment needs to be tagged in some way so it will not be printed several times. You need to do this using a Google Apps Script. I have already done a small part of this. The following Google Apps Script will access attachments that are received in a gmail address: [login to view URL] The following API could be used to do the printing of the attachments: [login to view URL] A big uncertainty is whether you can make this work for attachments of most types. We at least need it to work for .doc, .docx and .pdf. You also need to handle errors (attachments that could not be printed), so these emails are tagged with an "error" tag. I also do not know how to do the authentication for Google Cloud Print from Google Apps Script so you need to figure this out. Utilizing a Linux server and some PHP/Python code is an option for handling this part. Max price for this project is: 175$ If you take this project, I need to see some sort of result after 24 hours. That result does not need to work, but it needs to show that you are working on this.
