WirelessRawPrintHelper

A tiny helper library to extend raw priting on Windows CE based (CE, Embedded, Mobile etc.) devices.

Dependencies

.Net Compact Framework 2.0 or higher

Quick Start

Download the binary and add it as Reference to your project. Add using directive using WirelessPrintHelper; Now you can use it:

TcpIp

private void TcpIpPrint(string ip, decimal port, FileInfo filename)
{
	using (IWirelessPrinter btpHelper = new TcpIpPrinter(ip,(int)port))
	{
		btpHelper.Print(filename);
	}
}

Bluetooth SPP

private void BtSppPrint(string port, FileInfo file)
{
	using (IWirelessPrinter btpHelper = new BtSppPrinter(port))
	{
		btpHelper.Print(file);
	}
}

Sample

A) Parameterized printing

This approach is susitable for payloads that are similar to each other. Consider the following CPCL command sets:

Non-Parameterized

! 0 200 200 400 1
LABEL
CONTRAST 0
TONE 0
SPEED 3
PAGE-WIDTH 400
GAP-SENSE
PREFEED 0
POSTFEED 0
PRESENT-AT 0 2
T 7 0 10 10 My Sample Product
T 7 0 10 40 PC-01
BT 7 0 5
B EAN13 2 1 100 7 80 8693332221117
BT OFF

PRINT

Parameterized

! 0 200 200 400 1
LABEL
CONTRAST 0
TONE 0
SPEED 3
PAGE-WIDTH 400
GAP-SENSE
PREFEED 0
POSTFEED 0
PRESENT-AT 0 2
T 7 0 10 10 <ProductName>
T 7 0 10 40 <StockCode>
BT 7 0 5
B EAN13 2 1 100 7 80 <Barcode>
BT OFF
FORM
PRINT

In parameterized version we have replaced values of our fields with a placeholder.

Value	Placeholder
My Sample Product	<ProductName>
PC-01	<StockCode>
8693332221117	<Barcode>

By doing this we have created a template for our printing task. Now nefore printing we can dynamically set desired values.

private byte[] PrepareContent(string filename)
{
    // Prepare content parameters and their values
    // Parameters are <ProductName>, <StockCode> & <Barcode>
    // see afterParameterizing.LBL contents
    IContentParameters param = new ContentParameters();
    param.Add("<ProductName>", "My Sample Products");
    param.Add("<StockCode>", "PC-01");
    param.Add("<Barcode>", "8693332221117");

    // Read payload file
    IFileContentReader reader = new FileContentReader(filename);
    byte[] payload = reader.ReadAllAsByte();

    // Do the replacing
    IContentReplacer replacer = new ContentReplacer(param, Encoding.UTF8);
    return replacer.Replace(payload);
}
