We have a couple of emails from clients who experience stability issues after the update to version 1.4.0. It seems to be related to the use of the Epson ePOS SDK printer driver. For now, a perfect solution is to use the ESC/POS printer driver. Have a look in your data -> printers -> <all your printers> -> general -> type printer, change all your printers to ESC/POS if you had Epson ePOS SDK used before.

Change Epson ePOS SDK to …

esc:pos

… ESC/POS!
