Based on the documentation description :"NamePLU - 30 symbols for article's name plus separator for MU=60h"

B4X:

If PLUName.Contains(" ") Then
        PLUName= Regex.Replace(" ",PLUName,"\<")
    End If

You don't need to escape the “<"

B4X:

 PLUName= Regex.Replace(" ",PLUName,"<")

I think it is useless to post the project , because my app communicate with an API witch is connected to a cash register.
This is the the documentation

XML:

<Command Name="SellPLUwithSpecifiedVAT" CmdByte="0x31">

  <FPOperation>Register the sell (for correction use minus sign in the price field) of article with specified name, price, quantity, VAT class and/or discount/addition on the transaction.</FPOperation>

  <Args>

    <Arg Name="NamePLU" Value="" Type="Text" MaxLen="36">

        <Option Name="VAT Class C" Value="C" />

        <Option Name="VAT Class D" Value="D" />

        <Option Name="VAT Class E" Value="E" />

      <Desc>1 symbol for article's VAT class with optional values:

  </Args>

</Command>

Below you can see the main part of communication

B4X:

Sub Submit_Action(command As String)As ResumableSub 
    'Dim command As String = "SellPLUWithSpecifiedVat(NamePLU=Article1,OptionVATClass=A,Price=10.2,Quantity=1,DiscAddP=0,DiscAddV=0)"
    Dim command As String = command' "CashPayCloseReceipt()"
    Dim su As StringUtils
    command = su.EncodeUrl(command, "UTF-8")
    Dim j As HttpJob
    j.Initialize("",Me )
    j.Download("http://localhost:4444/" & command)
    Wait For(j) JobDone(j As HttpJob)
    If j.Success Then
        Log(j.GetString) 
        Return Code
    End If
    j.Release
End Sub

B4X:

Public Sub sellItem(PLUName As String,VATRate As String,UnitPrice As String,quantity As String,DiscProc As String,DiscVal As String) As String
    If PLUName.Contains(" ") Then
        PLUName= Regex.Replace(" ",PLUName,"<")
    End If
    Return $"SellPLUWithSpecifiedVat(NamePLU=${PLUName},OptionVATClass=${VATRate}$,Price=${UnitPrice},quantity=${quantity},DiscAddP=${DiscProc},DiscAddV=${DiscVal})"$
End Sub

I mean that you post a snippet like this

B4X:

 Dim PLUName as String="TEST 3"
 PLUName= Regex.Replace(" ",PLUName,"<")
 log(PLUName)

what is the result?

Here is the log result : TEST<3
And here is the printed line by device :

Can you not just use

B4X:

PLUName = PLUName.Replace(" ","+")

As you said it replaces spaces with '+' not a '<'

As it is sent to a web address you may find you need to send

B4X:

PLUName = PLUName.Replace(" ","%20")

Have a look at url encoding for which chars can appear in a web address line.
