So just call the PrintDocument.Print Method (System.Drawing.Printing) | Microsoft Docs[^] instead of specifically showing the print preview.

Yes, it uses the same code as Print Preview, just with a different destination.

ok i try with this code PrinDocument.Print(); if any problem occur then i will share with you

No, PrintDocument is a class - you need an instance.
printDocument1.Print();
Should do it.

i create connection in my App.config file
the connection string is
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionstrings>
<add name="dbx"
connectionString="Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename='|DataDirectory|\db\RetilShop_POS;Integrated Security=True"
providerName="System.Data.SqlClient"/>

<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />

Try looking here:
https://www.codeproject.com/Tips/1198443/Simple-SQL-Connection-String-Creation
It seems to be complaining at the semicolon, which is unusual. Also use the debugger to find out exactly what is in your string, rather than assuming you read it correctly from config.
