Blue Bamboo P25 Printer Android Demo Application With Source Code

February 28, 2014 by Lorensius Londa 22 Comments

Blue Bamboo P25 printer is a lightweight and portable thermal printer that provides low cost printing in mobile and wireless environments. It supports mobile application printing over Bluetooth, USB or Serial port (RS-232). It also has a good connectivity with Android device, makes printing from Android becomes very easy and fast.

Blue Bamboo also provides a sample Android project to show how to build an application that supports printing using P25 printer over Bluetooth. The source code itself is quite old so i made a slight modification with fresh UI and easy to read source code so developers can easily implement the codes into their projects.

This sample code shows how to print text, image, barcode and receipt into P25 printer using Bluetooth connectivity. The source code is available on Github repo, you can find it at the bottom of this post.

Print Text

private void printText(String text) {
	byte[] line 	= Printer.printfont(text + "\n\n", FontDefine.FONT_32PX, FontDefine.Align_CENTER, (byte) 0x1A, PocketPos.LANGUAGE_ENGLISH);
	byte[] senddata = PocketPos.FramePack(PocketPos.FRAME_TOF_PRINT, line, 0, line.length);

	sendData(senddata);
}

Use Printer.printFont(String content, byte fonttype, byte fontalign,byte linespace, byte language) method to format and position the text. For font types and text alignment, see FontDefine.java and for language definition, see PocketPos.java. Also call the PocketPos.FramePack(byte typeFrame, byte[] srcBuff, int srcOffset, int srcLen) to create frame data before sending to printer.

See P25 development guide page 60-63 for more information.

Print 1D Barcode

private void print1DBarcode() {
	String content	= "6901234567892";

	byte[] formats	= {(byte) 0x1d, (byte) 0x6b, (byte) 0x02, (byte) 0x0d};
	byte[] contents	= content.getBytes();

	byte[] bytes	= new byte[formats.length + contents.length];

	System.arraycopy(formats, 0, bytes, 0, formats.length);
	System.arraycopy(contents, 0, bytes, formats.length, contents.length);

	sendData(bytes);

	byte[] newline 	= Printer.printfont("\n\n",FontDefine.FONT_32PX,FontDefine.Align_CENTER,(byte)0x1A,PocketPos.LANGUAGE_ENGLISH);

	sendData(newline);
}

1D barcode printing format is: 1d 6b 02 0d [barcode data]. So to print “6901234567892” barcode data, the bytes would be:

{(byte) 0x1d, (byte) 0x6b, (byte) 0x02, (byte) 0x0d}
+
“6901234567892”.getBytes()

See P25 development guide page 59-60 for more information.

Print 2D Barcode

private void print2DBarcode() {
	String content 	= "Lorenz Blog - www.londatiga.net";

	byte[] formats	= {(byte) 0x1d, (byte) 0x6b, (byte) 0x10, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00,
						  (byte) 0x00, (byte) 0x1f};
	byte[] contents	= content.getBytes();
	byte[] bytes	= new byte[formats.length + contents.length];

	System.arraycopy(formats, 0, bytes, 0, formats.length);
	System.arraycopy(contents, 0, bytes, formats.length, contents.length);

	sendData(bytes);

	byte[] newline 	= Printer.printfont("\n\n",FontDefine.FONT_32PX,FontDefine.Align_CENTER,(byte)0x1A,PocketPos.LANGUAGE_ENGLISH);

	sendData(newline);
}

2D barcode printing format is: 1d 6b 10 00 00 00 00 00 1f + barcode data. So to print “Lorenz Blog – www.londatiga.net” text, the bytes would be:

{(byte) 0x1d, (byte) 0x6b, (byte) 0x10, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x1f}
+
“Lorenz Blog – www.londatiga.net”.getBytes()

See P25 development guide page 60 for more information

Print Image

private void printImage() {
	try {
		byte[] formats	= { (byte)0x1B, (byte)0x58, (byte)0x31, (byte)0x24, (byte)0x2D };

		//bluebamboo logo
		byte[] image = {(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00,(byte)0x00, ....... (byte)0x00};

		sendData(bytes);

		byte[] newline 	= Printer.printfont("\n\n",FontDefine.FONT_32PX,FontDefine.Align_CENTER,(byte)0x1A,PocketPos.LANGUAGE_ENGLISH);

		sendData(newline);
	} catch (Exception e) {
		e.printStackTrace();
	}
}

Image printing format is: 1B 58 31 xx yy + {image data in bitmap monochrome format} where xx is width in pixels/8 and yy is height of image in pixels.

So to print 200×45 pixels of image, the format would be :

{ (byte)0x1B, (byte)0x58, (byte)0x31, (byte)0x24, (byte)0x2D } + { bytes of bitmap monochrome image}

Width = 200pixels/8bit = 25 in decimals = 0x24 in hexa
Height= 45 pixels in decimal = 0x2D in hexa

See http://bluebamboo.helpserve.com/index.php?/Knowledgebase/Article/View/48 for more information on how to print image and P25 development guide page 18-13 and 63.

Print Sample Receipt

private void printStruk() {
		String titleStr	= "STRUK PEMBAYARAN TAGIHAN LISTRIK" + "\n\n";

		StringBuilder contentSb	= new StringBuilder();

		contentSb.append("IDPEL     : 435353535435353" + "\n");
		contentSb.append("NAMA      : LORENSIUS WLT" + "\n");

		String jpaRef	= "XXXX-XXXX-XXXX-XXXX" + "\n";
		String message	= "PLN menyatakan struk ini sebagai bukti pembayaran yang sah." + "\n";
		String message2	= "Rincian tagihan dapat diakses di www.pln.co.id Informasi Hubungi Call Center: "
						+ "123 Atau Hub PLN Terdekat: 444" + "\n";

		long milis		= System.currentTimeMillis();
		String date		= DateUtil.timeMilisToString(milis, "dd-MM-yy / HH:mm")  + "\n\n";

		byte[] titleByte	= Printer.printfont(titleStr, FontDefine.FONT_24PX,FontDefine.Align_CENTER,
								(byte)0x1A, PocketPos.LANGUAGE_ENGLISH);

		byte[] content1Byte	= Printer.printfont(contentSb.toString(), FontDefine.FONT_24PX,FontDefine.Align_LEFT,
								(byte)0x1A, PocketPos.LANGUAGE_ENGLISH);

		byte[] refByte		= Printer.printfont(jpaRef, FontDefine.FONT_24PX,FontDefine.Align_CENTER,  (byte)0x1A,

								PocketPos.LANGUAGE_ENGLISH);

		byte[] dateByte		= Printer.printfont(date, FontDefine.FONT_24PX,FontDefine.Align_LEFT, (byte)0x1A,
								PocketPos.LANGUAGE_ENGLISH);

		byte[] totalByte	= new byte[titleByte.length + content1Byte.length + refByte.length + messageByte.length +
		                	           content2Byte.length + message2Byte.length + dateByte.length];

		int offset = 0;
		System.arraycopy(titleByte, 0, totalByte, offset, titleByte.length);
		offset += titleByte.length;

		System.arraycopy(content1Byte, 0, totalByte, offset, content1Byte.length);
		offset += content1Byte.length;

		System.arraycopy(refByte, 0, totalByte, offset, refByte.length);
		offset += refByte.length;

		System.arraycopy(messageByte, 0, totalByte, offset, messageByte.length);

		System.arraycopy(message2Byte, 0, totalByte, offset, message2Byte.length);
		offset += message2Byte.length;

		System.arraycopy(dateByte, 0, totalByte, offset, dateByte.length);

		byte[] senddata = PocketPos.FramePack(PocketPos.FRAME_TOF_PRINT, totalByte, 0, totalByte.length);

		sendData(senddata);
}

		/*********** print English text*******/
		StringBuffer sb = new StringBuffer();

		byte[] web	= Printer.printfont(receiptWeb,FontDefine.FONT_32PX,FontDefine.Align_CENTER,(byte)0x1A,PocketPos.LANGUAGE_ENGLISH);

		byte[] totladata =  new byte[header.length + englishchartext24.length + englishchartext32.length + englishchartext24underline.length +
		                              + barcode.length
		                             + foot.length + web.length
		                             ];
	 	int offset = 0;
		System.arraycopy(header, 0, totladata, offset, header.length);

		offset+=web.length;

		byte[] senddata = PocketPos.FramePack(PocketPos.FRAME_TOF_PRINT, totladata, 0, totladata.length);

		sendData(senddata);
}

All bytes data to be printed is sent to printer using sendData method from P25Connector class (P25Connector.java)

private void sendData(byte[] bytes) {
	try {
		mConnector.sendData(bytes);
	} catch (P25ConnectionException e) {
		e.printStackTrace();
	}
}

P25Connector is a wrapper class to handle bluetooth operation (connect, disconnect, and bluetooth socket operation)

Hi have gotten a hand of your tutorial. But can’t print any image I pass unto Method getBytesFromAssets in the FileOperation Class.
The picture is located within the assets folder and still doesn’t work.

Great one Loresius,
From the source code when i printtext, reciept, barcode, or demo there extra strings printed before the actual print, do you know how they can be removed. eg printext > string (“Test”) will Print 1D456Test instead of just Test

Hello,

Sebelumnya saya ucapkan terkma kasih atas artkel blognya mengenai printer bluebamboo yg sdh diupload di github. Yang ingin saya tanyakan, apakah memungkinkan sdk tersebut digunakan untuk PHP web base system ?

Kasusnya begini: di tempat tersbut sudah memilikki aplikasi php web base , jadi rencananya, aplikasi web base tersebut mau dibuka di tablet dan kemudian print menggunskan portable pos bluebamboo. Apakah memungkinkan ?

Terima kasih sebelumnya

thanks for the tutorial. In your image printing, you said the image is 200px wide, but 0x24 is not 25 pixels (rather 36 px). I think you want 0x19.

Great post! It’s helping me a lot. Just bought BlueBamboo P10 bluetooth printer and thanks to this post I am able to print!

Now Dear Lorensius, how do you generate that hex string of the monochrome image?

Last, I printed the image once and on subsquent printing wierd string are being printed out instead of the image.

I’d appreciate your help on the above.

Thanks in advance.
