Android Question How to print Cent/Cedis Symbol with POS printer Xprinter XP 365B

mcqueccu · Aug 11, 2025

I recently bought Xprinter 365B Bluetooth/USB printer.

I am having problem printing the Cedis/Cent Symbol - GH¢ or ¢
Anyone using this same model or have can print the symbol should kindly help.

The following codes all did not work>

Bluetooth ESC/POS Printer Class

For the last couple of weeks I have been playing with an 80mm Bluetooth ESC/POS thermal printer I bought off eBay, new and delivered, for the ludicrously cheap price of £20. While the print quality, particularly of images with large areas of black (they are gray due to power supply or thermal...

Thanks @aeric and @Peter Simpson for your help. These printer gave me really hard time, and countless waste of paper. But if finally works.

I tried all the code pages, and your suggestions but it was not working. Later I switched to chatgpt. After a few back and forth and revisions, changing of FONTS, etc, it concluded that the font glyph was not matched properly, that it was using DOUBLE BYTE MODE.

What it’s doing

0x1C 0x26 (FS &)
Tells the printer to start "Chinese character mode" (double-byte character mode).
This makes the printer interpret the next bytes as double-byte characters (like Big5 or GB2312), not single-byte ASCII.
0x1C 0x43 0x01 (FS C 1)
Sets the Chinese character...

Which code page you are using when print?
Do you see the character printer when doing Self Test?

In ESC/POS (Epson Standard Code/Printer Output System), the cent character (¢) is typically represented by the decimal value 162 or the hexadecimal value A2 in the IBM437 code page. To print it, you would use this value within your ESC/POS commands, often within a string sent to the printer.

Attached Image test 2.1 is the result from Self Test listing the code pages but when I set them it does not work.
I found a test software online, and when I click the Traditional Print (highlighted in Yellow) I see the symbol

mcqueccu · Aug 12, 2025

This is the result from the test software. Its printed as highlighted

This is the code jsp code I found inside the test software

Blank - empty space

it gives Blank - empty space like (GH )

I tried different codepages from 0 to 100. All showed empty

B4X:

     For i = 0 to 100
Printer1.Reset
    Sleep(1000)
    Dim cp As Int = i
    Printer1.CodePage = cp ' change this number to determine the codepage, see the printer manual
  
    Printer1.WriteString("Start of character set of Codepage " & cp & CRLF)
  
    Printer1.CharacterFont = 1
    Dim buffer(224) As Byte
    For i = 0 To 223
        buffer(i) = i + 32
    Next
    Printer1.WriteBytes(buffer)
    Printer1.WriteString(CRLF)
    Printer1.WriteString("End of character set of Codepage " & cp & CRLF & CRLF)
    Printer1.Reset
sleep(2000)
Next

Copilot suggested several subs like below (SORRY FORUM NOT ALLOWING ME TO POST THE CODE)

aeric · Aug 12, 2025

Have you tried using WriteString ?
e.g

B4X:

Printer1.WriteString("30¢" & CRLF)
Printer1.WriteString("60" & Chr (162) & CRLF)

Put a space after Chr or before opening bracket for some functions/keywords.

aeric · Aug 12, 2025

I tested with code page 16 okay

B4X:

Printer1.codepage = 16 ' Windows 1252

Printer1.WriteString("10" & Chr (162) & "- 20¢" & CRLF & CRLF)

Have you tried changing the code page to 850 or 1252 then printing HEX 9B or ASCII 155???

I always have to change the code page setting to 1252 when printing a Pound Sign (£) in my apps.

Enjoy...

I will try the suggestions and report back.

Thanks @aeric and @Peter Simpson for your help. These printer gave me really hard time, and countless waste of paper. But if finally works.

I tried all the code pages, and your suggestions but it was not working. Later I switched to chatgpt. After a few back and forth and revisions, changing of FONTS, etc, it concluded that the font glyph was not matched properly, that it was using DOUBLE BYTE MODE.

What it’s doing

0x1C 0x26 (FS &)
Tells the printer to start "Chinese character mode" (double-byte character mode).
This makes the printer interpret the next bytes as double-byte characters (like Big5 or GB2312), not single-byte ASCII.
0x1C 0x43 0x01 (FS C 1)
Sets the Chinese character system to Big5 (0x01 = Big5, 0x00 would be GB2312).
This is why Notepad++ detects “Big5 (Traditional)”.
0xA2 0xE3
This is the actual Big5 encoding for the ¢ (cent) symbol.
In Big5, the byte pair A2E3 maps to U+00A2 (¢).
0x1C 0x2E (FS .)
Ends Chinese character mode, going back to single-byte mode.

After writing this code to cancel the Chinese mode, the other codes started to work

B4X:

    ' Full initialization + force CP850
    Dim initSeq() As Byte = Array As Byte( _
    0x1B, 0x40, _        ' ESC @   → Full reset (clear settings, reset mode)
    0x1B, 0x52, 0x00, _  ' ESC R 0 → Set international character set to USA
    0x1B, 0x74, 0x04, _  ' ESC t 4 → Set code page to CP850
    0x1C, 0x2E _          ' FS .    → Ensure Chinese mode is cancelled
    )

    ' Initialize printer to CP850
    Printer1.WriteBytes(initSeq)
  
    Printer1.WriteString("10" & Chr (162) & "- 20¢" & CRLF & CRLF)

    ' Now print the Cedi/Cent symbol in CP850
    Printer1.WriteBytes(Array As Byte(0x9B))
    Printer1.WriteString(" 5.00" & CRLF)

B4X:

Public Sub setCodePageFixed(codepage As Int)
    ' Build the ESC/POS sequence based on your fix
    Dim sequence As String
    sequence = ESC & "@" & _               ' Reset printer
               ESC & "R" & Chr ( 0 ) & _      ' International charset: USA
               ESC & "t" & Chr ( codepage ) & _ ' Set codepage dynamically
               FS & "."                   ' Cancel Chinese mode
    
    ' Send it to the printer
    WriteString(sequence)
End Sub
