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

Precede the Chinese text with chr (27) + chr(64)
B4X: Copy 
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: Copy 
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: Copy 
Printer.Initialize(Me,"Printer","GB2312")

B4X: Copy 
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: Copy 
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.
 
Update Rel.0.18
  • Add event: DataReceived(Buffer() As Byte)
  • Add new ESC_POS command: QueryPrinterStatus, QueryOfflineCauses, QueryErrorCauses, QueryPaperStatus

Some printers if you send certain commands tell you the status of the printer or if it is out of paper or other errors
 
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
 
Each label sends to the printer. It could be a buffer problem
 
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
