The printer may not print the MCR data using the echo option of the MCR command if the printer is not in line print mode.
Zebra RW Series Mobile Printers
If one chooses to use the ECHO option of the MCR command to print the data that is read by the MCR, one needs to insure the printer is configured for LINE_PRINT mode.
The printer can be configured for LINE_PRINT mode either by using the Label Vista utility or by sending the following command to the printer.
! U1 setvar "device.languages" "line_print"
