ABSTRACT:
A barcode printer system is shown having a host processing system in communication with a barcode printer. The host processing system converts multi-level user input printer commands into a data stream in the printer control language of the barcode printer for transmission to the printer. The host processing system stores a number of printer command function routines, each of which is associated with a number of multi-level user input printer commands. Each user input printer command includes format and data information in a single command. A low level user input printer command, however, may include only a user readable word and data, the host processing system automatically utilizing stored default values for the format information when converting the command. A higher level user input printer command may include an abbreviation designating the command and values for one or more format variables as well as data. The multi-level user commands are not fixed in length so as to be user friendly for low level users but flexible for higher level users.
