Constructor Detail

IBMCompatiblePrinterDriver

public IBMCompatiblePrinterDriver(OutputStream out,
                                  float charsPerInch,
                                  float linesPerInch)

Method Detail

setAutoLF

public void setAutoLF(boolean autoLF)

isAutoLF

public boolean isAutoLF()

getPrintQuality

public int getPrintQuality()

setPrintQuality

public void setPrintQuality(int printQuality)

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:

Parameters:

overflow -

Throws:

IOException - if there was an IOError while writing the command

flush

public void flush()
           throws IOException

Flushes the output stream.

Specified by:

flush in interface PrinterDriver

Throws:

IOException - if an IOError occured.

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.

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

Parameters:

chunk - the chunk that should be written

Throws:

IOException - if an IO error occured.

printEmptyChunk

public void printEmptyChunk(int count)
                     throws IOException

Prints an empty chunk. This is called for all undefined chunk-cells. The last defined font is used to print that empty text.

Specified by:

printEmptyChunk in interface PrinterDriver

Throws:

IOException - if an IOError occured.

printRaw

public void printRaw(byte[] raw)
              throws IOException

Prints some raw content. This content is not processed in any way, so be very carefull.

printRaw in interface PrinterDriver

Parameters:

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.

startPage

public void startPage(Paper paper,
                      String encoding)
               throws IOException

Resets the printer and starts a new page. Prints the top border lines (if necessary).

Specified by:

startPage in interface PrinterDriver

Throws:

IOException - if there was an IOError while writing the command

sendLineSpacing

public void sendLineSpacing(int lineHeight)
                     throws IOException

Defines the line spacing for the printer.

Parameters:

lineHeight - the height of a single line in points (1/72 inch).

Throws:
