public void setFontMapper(FontMapper fontMapper)

getPrinterSpecification

public PrinterSpecification getPrinterSpecification()

endLine

public void endLine(boolean overflow)
             throws IOException

Ends a new line.

Specified by:

endLine in interface PrinterDriver

Parameters:

overflow -

Throws:

IOException - if an IOError occures.

endPage

public void endPage(boolean overflow)
             throws IOException

Ends the current page. Should print empty lines or an FORM_FEED command.

Specified by:

endPage in interface PrinterDriver

Parameters:

IOException - if there was an IOError while writing the command

getCharactersPerInch

public float getCharactersPerInch()

Gets the default character width in CPI.

Specified by:

getCharactersPerInch in interface PrinterDriver

Returns:

the default character width in CPI.

getLinesPerInch

public float getLinesPerInch()

Gets the default line height.

Specified by:

getLinesPerInch in interface PrinterDriver

Returns:

the default line height.

flush

public void flush()
           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.

Specified by:

printChunk in interface PrinterDriver

raw - the content that should be printed.

Throws:

IOException

startLine

public void startLine()
               throws IOException

Starts a new line.

Specified by:

startLine in interface PrinterDriver

Throws:

IOException - if an IOError occures.
