We are trying to use the RESTful Engine to print reports (autotag templates). Currently, there is no feature to send a request for multiple copies of a job. If you need to print 3 copies of the same report, you will need to send the job 3 times. It will be great if you can command to have number of copies to print.
I am happy to tell you that this functionality was added in our recent releases! Please see our RESTful API documentation on how you can send a print job with multiple copies: https://ohana.windwardstudios.com/m/79043/l/1143629-16-5-0-report-engine-for-restful-api-reference
Thank you for your suggestion, and please submit any other ideas you have to improve our products.
