I haven't personally worked with this printer. But, here are my observations:
The driver used in this printer is ESC/POS, whereas the device type says the driver name as ESC/P. That must be the reason why printer controls aren't working as expected.
Since you copied ESC/P, the print controls copied are that of ESC/P, which has Line feed (SLINE) character as 0D0A.
Epson manual says, for ESC/POS, the line feed character is 0A. (https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=10).
Hence, please update the device type to 0A, and give it a try. If that doesn't work, try with 0D (https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=13), which is the code for carriage return.
Thanks,
Juwin
