Legacy Data Stream Interpretation
PALTM Print and Program capable printers uniquely address applications where upgrading to modern cost effective technology is desired. Often
Using a PALTM Print and Program capable printer solves this problem. In this case a PALTM program is written which interprets a data stream normally sent to the legacy device being replaced. This program is stored on the printer and is automatically executed each time the printer is powered on. This program is able to produce a new label format based on this legacy data. Even though the host computer is sending the exact same legacy data to the printer, the label format can be completely different. For example the new format may include bar codes, scaled and/or rotated fonts, lines, logo's etc. Even though the legacy device being replaced does not support these print abilities, the new label format can.
For example, text only outputs such as produced by a
