Printing at thermal printer works before. After firefox update itself to 82.0 version - printer roll out only 1cm of clean paper. At about:config was tried all: print_paper_height, print_paper_weight, print_shrink_to_fit, dosen other options. Printing works only if i set print.tab_modal.enabled to true. But i need silent print also, and with print.always_print_silent it's not working.

Can you create an account on https://bugzilla.mozilla.org/ and file a bug report there for the developers to investigate this?

Looks like this works for me: 1. go to about:config print.always_print_silent = false print.tab_modal.enabled = true print.save_print_settings = true

2. go to kasse and print check from kasse FE from firefox preview window

3. go to about:config again copy-paste all settings from - to print.printer_THERMAL_Receipt_Printer.print_paper_height -> print.print_paper_height print.printer_THERMAL_Receipt_Printer.print_paper_id -> print.print_paper_id print.printer_THERMAL_Receipt_Printer.print_paper_size_unit -> print.print_paper_size_unit print.printer_THERMAL_Receipt_Printer.print_paper_width -> print.print_paper_width

set print.save_print_settings = false print.always_print_silent = true

Most important second step - to set default paper size settings same as it was set for printer, without it printing does not work
