Hello is there any improvement?

After doing a search I found how to print the characters of different sets. I attach the example of Chinese:

Initialize the printer with this encoding

B4X:

Printer.Initialize(Me,"Printer","GB2312")

Precede the Chinese text with chr (27) + chr(64)

B4X:

Printer.AddBuffer_WriteLine(Chr(27) & Chr(64) & "艾德蒙 AOC E2450SWH 23.6吋")

Hello, I am having this problem too. It doesn't print all Turkish characters. Only ( Ç , ü , Ö , Ü ) printing these characters.
I want to write in the first line ( Çilek , Ördek , Ağaç ) but does not print ( Ç Ö ğ)
"Ş, İ, Ö, Ç, Ü, Ğ, ş, ı, ö, ç, ü, ğ" I want to print these letters. I've been researching for this for a few months but I couldn't figure it out.

Can you help me to solve this event?

B4X:

Printer.Initialize(Me,"Printer","iso-8859-9")

I choose Turkish option in the settings section of this application. It's using TrueTpye font.
The printer prints these characters. How can we activate this event in the library?

Hi @Ertan ,
The problem is probably related to your printer. I did the tests with mine and here are the results

B4X:

Printer.Initialize(Me,"Printer","GB2312")

B4X:

Printer.ClearBuffer
    Printer.AddBuffer_Writeline(ESC_POS.BoldOn & "Hallo dear" & ESC_POS.DoubleOff)
    Printer.AddBuffer_Writeline("How are you?")
    Printer.AddBuffer_Writeline("Fine thank's")
 
    Printer.AddBuffer_WriteLine("打印中文")
    Printer.AddBuffer_WriteLine("艾德蒙 AOC E2450SWH 23.6吋")

PS: Chinese = "GB18030"; Turkish = "GB2312"

Hi, How can print Greek Characters ?

It all depends on whether the printer contains this character set.
If the manual supports it, you must select the CODCE PAGE to activate the chosen character set

I tested it for a project today and it worked.
The problem is all about the character set of the printer.
if you too " ğ, Ğ, ş, Ş, ı, İ , ü, Ü, ö, Ö, ç, Ç " you want to print letters;

B4X:

Printer.Initialize(Me,"Printer","IBM857")

You should use IBM857.
Remember, if your printer still doesn't print these characters, you should correct this in your printer settings.

Where the printer sends some messages back to you.

Some printers if you send certain commands tell you the status of the printer or if it is out of paper or other errors

aeric · Dec 9, 2020

The spelling should be DataReceived

Tico.13 · Dec 18, 2020

Is there a way to set paper size, my app works fine but if i send to print more than 2 labels(paper) it starts to jump spaces

Star-Dust · Dec 18, 2020

Each label sends to the printer. It could be a buffer problem

See this post

SD: BT Printer Bluetooth

The example (Post#1) has been modified to illustrate how to print characters of a different font transformed into an image

www.b4x.com

or use CenterJustify method

Thanks! Appreciated.

To speed up processing I just placed the command: Printer.SelectFromMac("00:08:1B:95:42:BD") in B4A and the flow goes to Printer_ConnectedToPrint (Success As Boolean) as true.

1. In B4J (Printer.SelectFromMac("00081B9542BD")) it doesn't work, I have to search first. Is it possible to connect directly without have to search the device?
2. Is it possible to keep printing from both devices -Mobile and PC? . Do I have to logout the printer with "close" and search the printer again when I change the sender?

Tks a lot for the reply
