POS explorer and Receipt Printer

Question

When using POS explorer, everytime I claim my receipt printer it takes a few
seconds. My question is how can i claim the device at program startup then share
the device between forms? Meaning I want to open, claim and enable during
program startup then use the device on certain forms.  Is this doable?

Any Help would be greatly appreciated

Answer 1

In my book, I tried to show an MSR passing data to a second form. A printer as you describe might work if you call the main form that claims the printer. Just a thought.

Define static object in Program.cs, open and claim one time and use in all forms.

I've looked through several of your examples thank you for that.  On my main sales screen i through a popup window for the total and each time I go to print a receipt after committing the transaction it is a two second or so delay.  Is this standard operating procedure?  Meaning is it ridiculous to think I can do it quicker?

Example (only essentials):

Program.cs
==========

...
using Microsoft.PointOfService;
...

public static class Program
{
  public static PosPrinter posprn; // used as equivalent of global variable in C/Pascal
...
}

FormMain.cs
===
...
using Microsoft.PointOfService;
...

public class FormMain : Form
{
  public FormMain
  {
     InitializeComponent();
     try
     {
       PosExplorer pe = new PosExplorer();
       DeviceInfo di = pe.GetDevice(DeviceType.PosPrinter); // get default POS printer (must exist)
       Program.posprn = (PosPrinter)pe.CreateInstance(di);
       Program.posprn.Open();
       Program.posprn.Claim(5000);
       Program.posprn.DeviceEnabled = true;
       ...
     }
     catch (Exception ex)
     {
     }
  }
...
}

Thank you, I am using vb and this is working.  One last questions if you dont mind.  It takes approx 2 seconds for the recipt to start to print, then another delay before I print the second copy.  Is this by design since I am using POS.net and not using the manufactures driver?  I am using a Star TSP100 ECO

I think the delay comes from the printer or printer driver. You can look in POS4net log to see the times.

Answer 8

Where can this log be found, I do not need see it under Microsoft Point Of Service folder?

Enable logging in HKEY_LOCAL_MACHINE\SOFTWARE\POSfor.NET\Logging (Enabled key) and see the name and directory of logs.
