Printing with Epson TM-T82X

[akhil791]

Hi

I'm trying to use this 3" thermal POS printer on linux, and have installed Ubuntu 18.04 as the printer driver supports this version of the OS. When I print, it comes out small, and does not fill the full 3" width of the paper. I have attached a screenshot for reference. Can someone help me out. I have selected 80x200mm as the paper size, but in this dialog, it defaults to 72.32x200mm
