epson tm220 firmware flash-able ?
dear all,
we noticed in a simphony enviroment the Epson tmu-220 with Firmware ml5.10 does work fine.
but when this mainboard will be replaced by a version with ml5.01 or ml1.10 strange numbers suddenly showing up at the receipts.
are those mainboards with 'old firmware' to flash to the latest version? and where to find this version?
