Thermal Receipt printing (50% or half of the page)
For version 90.0 PC version, there is an issue with printing on 80mm thermal receipt printer. Seems like it is across almost all brands of thermal receipt printer.

Thank you for the screenshot.
I'm not sure whether Firefox has identified the proper paper size for your printer. Does it make sense to you that it says 48 column?
I notice the scaling is set to 30%. Could you switch back to "Fit to page width" and see whether Firefox can lay out the page correctly without manual scaling?
This thread could be the same issue:
Several bug reports have been filed about lost content when scaling is lower than 100%. Hopefully we'll get a fix or some kind of workaround soon.
A Firefox update (Firefox 90.0.2) has been released to fix this printing bug in Firefox 90. Release notes: https://www.mozilla.org/en-US/firefox/90.0.2/releasenotes/ (quote) Fixed truncated output when printing (bug 1720621)
