SYNOPSIS

pbmupc [-s1 | -s2] type manufacturer product check

pbmupc creates UPC-A (Universal Product Code) barcode images in PBM (Portable Bitmap) format. It takes the four components of a 12-digit UPC-A code as separate arguments: the number system type digit, a five-digit manufacturer code, a five-digit product code, and the check digit.The output PBM image can be converted to other formats using Netpbm conversion tools. UPC-A barcodes are the standard retail barcode format used in the United States and Canada.

manufacturer
