How to create a printpage in specific size

Good afternoon,
with my labelwriter from Dymo (https://www.staples.nl/labelwriter-450/cbs/1371153.html?price=incvat&gclid=CjwKCAjwkcblBRB_EiwAFmfyyzjUZrxntLre3-3X6vr1FrAhFcq-HZz4NsqqT-icw2s3cBCQ5XR4RRoC8_AQAvD_BwE)

I would like to print EAN codes from my products via PHPrunner. (9.8)
I bought the EAN plugin, which works fine in view mode, but how can I create a specific labelview that has exactly the correct needed sizes to print via the labelprinter? Is there maybe someone whoe already did this? whihc PHPrunner options should I use for such a page? (view, or report? or somethig else?)
Specifically, I would like to have a button near a product, that opens a page, where I can add a quantity, and then a submit button that makes the print of my product with the mentioned quantity of labels.
Hope someone knows how to do this.
Thanks!
