Let’s try a few other ideas.
Idea 1:
Under the location setting for this printer, try these settings:
https://ibb.co/10FkWZ0
Set the Custom Width to 0 MM
Now test this result.
Idea 2:
We want to have you try and modify the plugin source files, removing the margin setting for the template style sheet
Click Plugins > Plugin Editor > Select Print Manager > Select /Templates/Style.php
Now delete this code, https://ibb.co/6H3K9dd
@page {
margin: 0;
}
IMPORTANT: Since you are modifying plugin code, make sure you have a backup of the site prior to making this code change.
Now test this result.
Idea 3:
Reduce paper size settings in the Print settings on the operating system. Often you can ‘trick’ the printer by selecting a smaller paper size. For example, 56mm x 0mm. Try a smaller setting in the paper settings when you manager the printer on the OS.
Now test this result.
Let us know if any of these settings yield a better result. If possible, include a screenshot of the printed out receipt. We’d love to see the results and try to understand if we can optimize them better for this printer model.
