Constructor Detail

LinePrinter

public LinePrinter()

Create a TextPrinter object with the default type font and size.

LinePrinter

public LinePrinter(String name,
                   int size)

Create a TextPrinter object ready to print text with a given font and type size.

Method Detail

getCharsPerLine

public int getCharsPerLine()

Initialize the print job, and return the base number of characters per line with the established font size and font. This is really just a guess, because we can't get the font metrics yet.

doPrint

public boolean doPrint(String[] header,
                       String[] body,
                       boolean interactive)
                throws PrinterException

Print some text. Headers are printed first, in bold, followed by the body text, in plain style. If the boolean argument interactive is set to true, then the printer dialog gets shown. Either array may be null, in which case they are treated as empty. This method returns true if printing was initiated, or false if the user cancelled printer. This method may throw PrinterException if printing could not be started.

Throws:

PrinterException

print

public int print(Graphics graphics,
                 PageFormat pageFormat,
                 int pageIndex)
          throws PrinterException

Perform printing according to the Java printing model. NEVER CALL THIS DIRECTLY! It will be called by the PrinterJob as necessary. This method always returns Printable.NO_SUCH_PAGE for any page number greater than 0.

Specified by:

print in interface Printable

Throws:

PrinterException

main

public static void main(String[] args)

Main method for testing. This main method sets up a header of "PRINTER TEST" and reads System.in to get body text.
