One of our summer interns has stayed on during the school year to work some weekends on special assignments. This past weekend, her assignment was to draft, and try out, procedures for scanning all incoming regular mail including the envelopes. This is a new effort for us because previous mail handling was done by another organization. Most of our incoming mail is from other businesses that create printed address labels. Many of these labels also have a type of bar code below the address. Is there a Linux utility or standard application that will read and translate these codes. Thanks.
