[Koha] barcodes- can ordinary printer be used?

we have successfully intalled koha for windows 2.2.8 and we are currently testing and customizing to fit our needs. we have generated some barcodes using the normal printer but these barcodes cannot be read by the barcode reader. Do we have to use special printer to print barcodes? please help. thanks ken rotich kenrotich2003@yahoo.com --------------------------------- Be a better pen pal.
