I am trying to print CPCL commands in toshiba printer using c# tcpclient socket programming.

this is my code

System.Net.Sockets.TcpClient client = new System.Net.Sockets.TcpClient();
      client.Connect(ipAddress, port)
      StreamWriter writer = new StreamWriter(client.GetStream())
      string printtemplate="! 0 200 200 300 1

                            PAGE-WIDTH 396

                            T 4 1 10 80 £75

                            T 4 1 140 80 £75

                            T 4 1 280 80 £75

                            FORM

                            PRINT" ;
                            byte[] unicodeBytes =   Encoding.Unicode.GetBytes(printtemplate);
                            byte[] win1252bytes =  Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(1252), unicodeBytes);
                            writer = new System.IO.StreamWriter(client.GetStream());
                           string win1252String =  Encoding.GetEncoding(1252).GetString(win1252bytes);
                           writer.Write(win1252String);
                         writer.Flush();
                       writer.Close();
                     client.Close();

What I have tried:

when i am trying to execute, it is printing u75 u75 u75 in toshiba printer. output should be £75 £75 £75 also it should support other country currency symbols like euro,doller and all.

Solution 1

Use the BinaryWriter class instead of the StreamWriter class and write the win1252bytes byte array:

C#

byte[] unicodeBytes = Encoding.Unicode.GetBytes(printtemplate);
// EDIT: From comments, the printer support ISO-8859-15 to show the EURO symbol
//byte[] win1252bytes = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(1252), unicodeBytes);
byte[] isoBytes = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(28605), unicodeBytes);
writer = new System.IO.BinaryWriter(client.GetStream());
// The Write(Byte[]) method will write data as they are
//writer.Write(win1252bytes);
writer.Write(isoBytes);

If the output is then still wrong, ensure that the printer is using the 1252 encoding.

Thanks for your reply.

but euro is not printing. it is printing ?75 ?75 ?75. expected output is €75 €75 €75

Jochen Arndt 18-Aug-17 5:40am

Euro? In your question you are using GBP.

If GBP is working but Euro not, check the manual of your printer. Is it really using Windows-1252 or ISO 8859-1? ISO 8859-1 does not contain all symbols (including Euro) from Windows-1252. If you need the Euro symbol, your printer must support ISO-8859-15.

See https://de.wikipedia.org/wiki/ISO_8859-1.
It shows the code points of the above encodings and explains the differences.
EDIT: Damn, I posted the German link and the English one does not explain the differences.

printer is supporting ISO-8859-15.. but euro is not printing. is there any other encoding to get euro??

Jochen Arndt 18-Aug-17 6:07am

Then you have to send him ISO-8859-15 encoded data. Just replace 1252 by 28605 (see https://msdn.microsoft.com/en-us/library/system.text.encoding(v=vs.110).aspx for code page numbers).

Member 8235434 18-Aug-17 6:15am

no luck. same issue.

Jochen Arndt 18-Aug-17 6:17am

Have you selected ISO 8859-15 at the printer?
You must send the data in the encoding actually selected (configured) at the printer.

Member 8235434 18-Aug-17 6:22am

I am using toshiba network printer(Label printer). No option to select in printer..

Jochen Arndt 18-Aug-17 6:30am

I don't know your printer model or have the manual present.

Just check it yourself:
Which encoding is supported?
If there are multiple encodings supported, how can they be selected?

Possible selection methods are: Keys on the printer, a configuration software , driver settings, or even sending specific commands. Check the manual.

Select the best matching encoding (preferrably Unicode like UTF-8).

Then send data in the matching encoding.

i am using toshiba portable printer b-ep2dl-gh40-qm-r

Jochen Arndt 18-Aug-17 7:31am

Do you expect that I get now the manual and check it for you?

As a programmer you should be able to do such.

Okay, a quick search shows that there are multiple options in the printer driver. You can select a Barcode Font and specify the encoding which seems to be Windows-1252 by default.

Then it should be possible to display the Euro symbol. But I don't have the printer and can't test it.
