Bought a used Ithaca POS printer to handle my POS system when I do shows. I use Windows 7 on a laptop and Imonggo as my POS system through a wi-fi connection. The older printer was serial thru usb that took forever to print while my customer stood by, so I bought this Ithaca on a USB thinking I could speed things along. The driver loaded fine and I can even test print and print a receipt through the POS system. However, the one page to control after printer codes to open the cash drawer continues to give me an error message and I cannot change the profile to "fire the cash drawer 1" because of the error. It shows up as a "lang mon registry error." I figured it is a language monitor (LM) registry error. I see that my LM version is displayed along with the driver version but I cannot identify how to change or correct the LM version or what the error actually is that is not allowing me to change the setting for the system to fire the cash drawer open after the receipt prints. Any help would be appreciated.
