iMZ320 Printer - Paper feeding issue

Hello,

I have a Zebra iMZ320 printer, but I have a couple of issues, when I try to print something, it feeds a lot of paper before actually printing something, seems like it does that to reach 10in, since after changing the length from 10in to 5in, it started to feed up to 5in only, also, after changing the length, the Feed Button stopped working properly since now it feeds 5in of paper. This happens in my printing testing app, and in the Zebra's Printer Setup app (For example, when I try to print a test label).

The printer is in Receipt Mode, the Media Type is Continuous, the paper width is 2.84in.

How do I solve this? Do I have to calculate the length of the document I want to print and then change the configuration with the SDK? Why is it happening with the official app?

Best Regards, thanks in advance.
