The problem is that the printer is interpreting those escape codes - Epson printers have always set different character sets and done other functions by sending them ESC (CHR(27) plus additional codes. Either the cash drawer is supposed to intercept those commands and not pass them on, which could be a setting with the drawer hardware, or you need to see if the drawer accepts a different command to open it - some are configurable as to the activation string. CHR(27)+CHR(112) happens to be the Epson command to toggle proportional mode printing. The NUL (CHR(0)) and ENQ (CHR(5)) probably print out as graphics characters.
