I am Trying to print a bar code via sap script. we are using oki data dot matrix printer. When i try to print the bar code is not printing but in print preview the bar code is appearing. for that i created a custom device type and assign bar code to that device type and created a suffix and prefix assigned the print controls to that device type which i am using. i checked the print preview the bar code is appearing. but after giving print the bar code is not printing. I am using oki341( also used EPESCP9) device type for that oki dot matrix printer. I also contacted oki data technical team if it is support the bar code printing in sap they said yes. Any suggestions what am i missing and suggest me the procedure to get to print the bar code.
