How i can transsmit order with uart?

Using Arduino Programming Questions
1

hello every one
i have a thermal printer with cutter for paper
i use it for printing text en barcode and other thing
now i use it on one project and i don't find any information for do ordering it to cut paper when is end
this printer is work with UART interface with bauderate (4800) mark masung Inc
on arduino ide if we use e.g ;

Serial.print(0x1B,0x69);

or something else with print is just print it on the paper not other thing do
what exactly the command necessary for do order with UART interface not just send text

on the document technic i find those line

2.7.1 Transmit command (sending )
[interface]
int PrintTransmit(const char* bCmd,int iLength)
[function]
Transmit original command to printer
[parameter]
name
type
parameter description
bCmd
char*
command
iLength
int
command length
[return value]
0 success
1 failure
[sample]
char bCmd[2]={0x1B,0x69}; //cutting command
int r = PrintTransmit(bCmd,2);

and the complet document for this printer is :
MASUNG printers SDK reference manual-V2.2.pdf (750.7 KB)

Take a look at Serial.write()

More like

all file included on the folder for this priner is her ;

Windows DLL V2.2.2.5.zip (3.4 MB)

its also like print

6

Please post an example that shows it is the same

7

that is text the printer just write that on printer

8

its same for the printer its write on the paper not applicant the order

The SDK reference manual seems to detail the high level function calls that you woukd use on Win or Linux. You need the document that details the low level instructions that the printer understands.

You may be lucky in that the seller has rebadged another manufacturers printer. You would probably need to look for some identifying model number on one of the internal boards.

I'm unclear whether that is a statement or question.

11

It's not clear from the document whether the PrintTransmit function applies additional bytes to the command or not. You could be missing an escape sequence.

No.

Predict what this will print, then try it:

void setup() {
Serial.begin(115200);
while(!Serial);
Serial.print("\x43\x45");
}

void loop() {
}

its clear that line ( RS-232 / TTL / USB ) for TTL
i dont know what meaning this secret about those type of product i dont find any other information about this printer
his sitweb is

A shot in the dark, but have a look at:
https://escpos.readthedocs.io/en/latest/home.html
It's not your printer model but I suspect that they all share a fairly common set of commands.

If you look in the Print Movement section you will see the command for Partial Cut, which is 0x1B 0x69. The same as mentioned in your post #1.

I'm guessing that you would simply code something like:

Serial.write( 0x1B );
Serial.write( 0x69 );

According @farai

I am not inclined to believe it, but he/she has not provided any proof
