cmd_feed_paper, cmd_set_energy, dark_mode seem to have no effect

When trying to implement cmd_set_energy and cmd_feed_paper in my own application, changing the values used in cmds_print_img function appears to have no effect. The paper doesn’t feed any further, and/or the text is not any darker if I increase the values in these fields.

Printing a demo page from the iOS App (or the built-in debug QR code print mechanism) provides much darker prints than printing a black text on white BG PNG from catprinter. I suspect that these values are not being properly set when I print from the function vs. the App.

Printer model: GB02

Hello, i am using the GB03 model and I can also say that using the original Android App prints way better than using the python script. I have tried to add the cmd_set_energy and/or CMD_PRINT_TEXT, but didn’t improved the printing quality.
