[@andrewpham9116]

Hi, I try your PrinterUtility NutGet work great for 32bits application. But my application build on 32 and 64bits on Visual Studio 2015. Do you have 64bit version? Can I have the source code or buy from you?

[@techsapphire]

yes please, kindly reach me at [e-mail]

@@techsapphire I had some error too. My application build on 32 and 64 bits.

Hi Sir is there a function that I could check the status of the printer? Eg. out of paper / offline / etc. Upon checking and debugging the code "OpenPrinter" function always return = TRUE even the printer is not power ON. please sir email for the response on.

[@lifesuccess7376]

Nick Marquez have you resolved this

[@techsapphire]

Hi sorry, I missed this comment. You can query list of printers and check whether it contains your printer. If not, than it is not online. System.Drawing.Printing.PrinterSettings.InstalledPrinters

Code128 not accepting the http link or the text form of data. Do we need to create own code for the same and if yes, if i create the own barcode and convert into byte[] then will it print?

[@techsapphire]

Use code39 public byte[] Code39(string code)
{
int height = 300;
var command = new List {0x1D, 0x68, (byte)height, 0x1D, 0x77,(byte)2,0x1D, 0x6B, 0x45, (byte)code.Length };
command.AddRange(code.ToCharArray().Select(x => (byte)x));
return command.ToArray();
}

[@abdullahsaleem8757]

Sir I am having an issue. i.e.
When printer is attached, it does not print anything but if printer is not attached it sends document to the printer queue and when printer is attached, the queue empties without printing anything.
I tried using "Microsoft Print to PDF" but it generated an empty file.
Please help me with this issue.

[@techsapphire]

You need actual POS printer to test it. As escpos commands cannot be previewed. Else check ruclips.net/video/osI7P1YdL3o/видео.html

Barcode does not print with this. Could you please let us know a workaround

Try print with below code, without temp file:
public static bool SendValueToPrinter(string szPrinterName, Byte[] BytesValue)
{
Byte[] bytes = BytesValue;
bool bSuccess = false;
// Your unmanaged pointer.
IntPtr pUnmanagedBytes = new IntPtr(0);
int nLength = 0;
nLength = Convert.ToInt32(bytes.Length);
// Read the contents of the file into the array.
// Allocate some unmanaged memory for those bytes.
pUnmanagedBytes = Marshal.AllocCoTaskMem(nLength);
// Copy the managed byte array into the unmanaged array.
Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength);
// Send the unmanaged bytes to the printer.
bSuccess = SendBytesToPrinter(szPrinterName, pUnmanagedBytes, nLength);
// Free the unmanaged memory that you allocated earlier.
Marshal.FreeCoTaskMem(pUnmanagedBytes);
return bSuccess;
}
//RawPrinterHelper.SendValueToPrinter(PrinterName, BytesValue);
