Had to uninstall drivers on both printers and reinstall till it ask to turn on printers, then started sambapos and edit printer ticket/ kitchen to oem 437 and is now working. On com2 and usb ports. I did the print test from each printers property page, then went to sambapos.
Had to change Baud rate to 9600 for serial, as it was showing ‘19200’ and not sure if usb is unlimited, as I did not change anything, as no option under usb, but Feed Test shows as ‘38400’.
