[Myo Thura Lwin]

Hi,

I face one problem of pos printer.
This is my first time of using pos printer so I cannot solve the error of epson pos printer TM-U220A with 9 pin to 25 pin Serial Connection.
I test with "CheckHealth Test" and it shows the Exception Information as below.


ErrorCodeExtended : 1001

I will use that printer with C# language in Visual Studio 2005.

I also attach two files which show the settings of Pos Printer.
So, what settings do I need to make?
So, please help me.

Thank you.

Hi,

I attach a zip file that contains a doc file with the images of settings.
I hope, you can see the settings of printer by making download the doc file.

I only test with "CheckHealth Utility" .
This test application is sample program for printer whether it works properly or not.
I haven't used that printer in sale system yet.
I just only test with sample program that my settings are right or not.
I think, I cannot configure the settings correctly.
The error message is described previously.
And I can show only these information. Sorry for that.

Thank for your help.

Message : The port is being used by the other system.

May be it's something with your COM1 port?
Try to connect it to another one.

I was just going to say that the error message says it all:
The port is being used by the other system.

Another program is using COM1

• That might be the O.S. if there is a Windows driver trying to control it, while you are trying to access it directly.
• It might be the POS sales software trying to control it, while your second application is trying to talk to it.
• It might be that your application opened it... then tried to open it a second time... without closing it.

Hello ,
Thank you for your answers.

Now, I would like to know one thing.
In the user guide of printer, it describes that "Epson Terminal Printer Driver" must be installed first.
So, what is terminal printer driver and how to get it?


Thank you.
