Printing RDLC Report Using Asp.net C#

Hello everyone, hope someone can give me the correct code.

I am trying to print a RDLC report without preview. Below is my code but does not work. The error says "Exception Details: System.NotSupportedException: The given path's format is not supported."

protected void PrintPos(object sender, EventArgs e)
{
string sql = "spGet_SalesDetails_A4Printing";
var dt = GetDataTable(sql);
LocalReport report = new LocalReport();
string path = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
string fullpath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Remove(path.Length - 4) + @"\PosPrinting\PrintingPos.rdlc";
report.ReportPath = fullpath;
report.DataSources.Add(new ReportDataSource("dsProduct", dt));
int printQty = 2;
for(int i = 0; i < printQty; i++)
{
PrintToPrinter(report);
}
}

I am following this post: https://ashproghelp.blogspot.com/2017/01/how-to-print-directly-without-showing.html

While debug check fullpath path string is correct or not then your remove path.Length - 4 why this creates wrong path i have checked it
