Post function to print barcode of a custom field onto the network printer

Question

Hello everyone,

I am building an inventory management system in JIRA. To automate a few processes and to avoid manual errors we use barcodes. Now, we need an option to generate a barcode based on a custom field value and send that barcode for a print on the network printer using a post function call with Scriptrunner.

Please let me know how do I go about doing this.

Interesting use case!

You can definitely implement it based on this idea:

* Use the barcode feature of the Better PDF Exporter app. Basically, if you don't want anything else, but the barcode itself, create a PDF template that contains nothing else, but the barcode. The app allows encoding any information, including custom field values, in the barcodes! See this tutorial.* Extra hint: you can customize your template from the default issue-fo.vm by dropping all fields and turning the QR code to the barcode you need. (See the screenshot at the bottom.)

* Then implement the post function in ScriptRunner which renders the PDF with the barcode. It is also simple, see this second tutorial.
* Now you have the PDF document in the Groovy script, triggered by the post function. You will send that to the print. I don't actually know how to do this, but I guess it would copying the bytes to some source that is consumed by the printer.
