using printer device fonts

[simo_mon]

I have written a POS system which uses the SAM4s ellix 20 printer.

The problem is that receipts are printing far too light, i contacted the manufacturer and they said that i should use the device fonts rather than graphics based fonts.

Is there any way in java to

a) determine the type of font that the printer is using

b) print a line using the printers "device font"


thanks in advance

ok i have a way to get printer attributes, but i still can't get anything like the
printers font ? any suggestions

public void printAttrbutes(PrintService printService)
	{
		 System.out.println("Printer Name is (" + printService.getName()+ ")" );

		 PrintServiceAttributeSet printServiceAttributeSet = printService.getAttributes();

		 
		 Attribute[] array = printServiceAttributeSet.toArray();
		
		 
		 
		 System.out.println("PrinterLocation is (" + printServiceAttributeSet.get(PrinterLocation.class));

		 System.out.println("PrinterInfo is (" + printServiceAttributeSet.get(PrinterInfo.class));

		 System.out.println("PrinterState is (" + printServiceAttributeSet.get(PrinterState.class));

		 System.out.println("Destination is (" + printServiceAttributeSet.get(Destination.class));

		 System.out.println("PrinterMakeAndModel is (" + printServiceAttributeSet.get(PrinterMakeAndModel.class));

		 System.out.println("PrinterIsAcceptingJobs is (" + printServiceAttributeSet.get(PrinterIsAcceptingJobs.class));
		
		
		 System.out.println("PrinterIsAcceptingJobs is (" + printServiceAttributeSet.get(PrinterIsAcceptingJobs.class));
			
		
		
	}

thanks for the heads up :) and sorry didn't occur to me that this was bad :)

everyone i "cross posted" this on the above link and i will cross post the solution.. once i get there :)

this is probably in the class of " your on your own with that one " so i'll put up what i got in case someone else is struggling :)


i worked out a way to communicate directly to the printer by sending stuff ( hex codes ) to COM1 BUT !!! this only works windows and on the machine that the printer is connected to :(

code #1

public class PrintDriver {
	
	public static final int  CR = 0x0D;
	public static final int  PRINT_AND_LINE_FEED = 0x0A;
	


        public static void main(String [] args)
	{
        String com1 = "COM1";
		
		try {
		      FileWriter out = new FileWriter(com1);
		     
		   
		      setCharacterSize(out);
		      
		      for(int i =0;i<5;i++)
		      {	
			      out.write("1 Latte         $3.50");
			      out.write(PRINT_AND_LINE_FEED); 
		      }
		      lineFeed(out,10);
		      setAutoCutter(out);
		      out.close();
		      }
		    catch (IOException e) {
		      e.printStackTrace();
		      
		      
		      
		      }

         }

private static void setAutoCutter(FileWriter out) {
		if(out!=null)
		{
			try
			{
						
					out.write(0x1D);
					out.write(0x56);
					out.write(1);
							
				
			}
			catch(Exception e)
			{
				
				System.out.println(e.getMessage());
			}
			
			
		}
		
	}



	private static void setCharacterSize(FileWriter out) {
		if(out!=null)
		{
			try
			{
						
					out.write(0x1D);
					out.write(0x21);
					out.write(1);
							
				
			}
			catch(Exception e)
			{
				
				System.out.println(e.getMessage());
			}
			
			
		}
		
	}

	private static void lineFeed(FileWriter out, int numberOfLines) {
		
		if(out!=null)
		{
			try
			{
				
				for(int i =0;i<numberOfLines;i++)
				{
					out.write(PRINT_AND_LINE_FEED);
					
				}
				
			}
			catch(Exception e)
			{
				
				System.out.println(e.getMessage());
			}
			
			
		}
		
		
		
	}

i have also worked out how to use the java printing stuff so that it uses the "printer defined font"

code #2

public static void main(String [] args)
	{
		System.out.println(" PrintDriver");
		
		
		PrintService defaultprinter = PrintServiceLookup.lookupDefaultPrintService();

		DocPrintJob job = defaultprinter.createPrintJob();
		
		
		DocFlavor  flavour = DocFlavor.BYTE_ARRAY.AUTOSENSE;
		
		String message = "hello\n";
		byte[] b = message.getBytes();

		Doc doc = new SimpleDoc( b, flavour, null);
		try {
			job.print(doc, null);
		} catch (PrintException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}

so the above code will use the default font for the printer, which is the "DocFlavor.BYTE_ARRAY.AUTOSENSE" part....

what i am trying to do now is combine part1 code with part2 code...

ie i am trying to send hex values to the printer using code like part2

Iv'e got a really ugly solution which is using an rmi server to call com1 on the correct machine but i want to try to avoid using it ???

any help or insight would be appreciated :

thanks again

and sorry for the un announced cross posting !
