Hi, the postbox on Raspberry PI 4 not working with the image for Odoo v10. Any feedback?

I tried the package from plinth666 in github but the raster wasn't quite proper and the print timing was quiet long.

I used then a bunch of free code from Epson, a PPD file from another printer and modify them to produce this new package: https://github.com/groolot/epson-tm-t88v-driver

Better rasterization, cash drawer and buzzer, all is operational.

In Odoo 13, I had to change the receipt scaling to 90% in order to see everything on paper by modifying the point-of-sale module CSS

 /usr/lib/python3/dist-packages/odoo/addons/point_of_sale/static/src/css/pos.css

The modification is:

--- pos.css.orig
+++ pos.css
@@ -1462,6 +1462,7 @@
 }
 
 .pos .pos-receipt-container > div {
+    transform: scale(0.9);
     text-align: left;
     width: 300px;
     background-color: white;

Hope that could help someone like I was: in pain.

yes it should work smoothly
