Abstract
A host computer and printer and method of operation wherein the data file describing a document is processed in a manner that creates a frame of data to be transmitted from the host computer to the printer. The data frame contains a data stream which is wrapped in a create font command wrapper so that the printer will be able to process the data frame in some manner. If the printer is operating in a first mode and cannot process the actual stream data, the frame wrapper will allow the printer to process the wrapper and ignore the data stream. If the printer is operating in a second mode and can process the actual data stream, the printer ignores the wrapper and processes the data. The printer will print a message to the user if the printer cannot process the actual data stream. The message informs the user of the printer's inability to process the data stream.
