           throws IOException

Flushes the output stream.

Specified by:

flush in interface PrinterDriver

Throws:

IOException - if an IOError occured.

printChunk

public void printChunk(PlaintextDataChunk chunk)
                throws IOException

Prints a single text chunk at the given position on the current line. The chunk should not be printed, if an previous chunk overlays this chunk.
