Does ErpNet.FP support fiscal printers registered in North Macedonia?

[21studiohd]

Does ErpNet.FP support fiscal printers registered in North Macedonia? Specifically Daisy FX 1300 / Perfect S 01 with the MK protocol. Does the Daisy driver handle the Macedonian fiscal receipt format and uniqueSaleNumber requirements correctly, or is it Bulgaria-only?

You have two options:
Option 1: Fork the repository and replace the 'BG'/'bg' protocol prefix with 'MK'/'mk' throughout the codebase.
Option 2: Wait for the ErpNet.FP maintainers to implement a configurable protocol prefix. This setting would default to 'BG', but could be configured by the user to 'MK' or another value.
Depending on this prefix, the implementation will use different dialects, though the main structure and core functionality will remain identical. When the fiscal protocol was originally designed, the 'BG' prefix was introduced specifically to allow for future extensibility. Therefore, now might be the perfect time to add support for additional prefixes.

Im sorry , but im not understanding your suggestion.
Im a newbie and i have made a restaurant pos system that i want to sell to one of my friends.... most of the part is ready but i cant integrate the terminal fiscal option to a print as a fiscal button isnide my webpage....
Here i learned that for the fiscal printer to work it needs to be sent this information: {
"uniqueSaleNumber": "DT279013-0001-0000001",
"items": [
{
"text": "Cheese",
"quantity": 1,
"unitPrice": 12,
"taxGroup": 2
},
{
"type": "comment",
"text": "Additional comment to the cheese..."
},
{
"text": "Milk",
"quantity": 2,
"unitPrice": 10,
"taxGroup": 2,
"priceModifierValue": 10,
"priceModifierType": "discount-percent"
},
{
"type": "footer-comment",
"text": "YOU ARE WELCOME!"
}
],
"payments": [
{
"amount": 30,
"paymentType": "cash"
}
]
}

But is this for bulagaria and macedonian or only for bulgaria ?
If macedonia uses different format how do i know what format to use ?
And for this information to be given I should have the restaurant dishes each have a tax group value and saved as macedonian text not english?
and also "uniqueSaleNumber": "DT279013-0001-0000001", should increment after each print?
I would appreciate any help possible thank you!

To answer your specific question: No, this library does not support North Macedonian (MK) fiscal devices out of the box.

Currently, the library is maintained by developers in Bulgaria and implements communication protocols strictly according to the documentation provided by manufacturers for the Bulgarian market.

However, the library's architecture is designed to support different protocol dialects. Extending this support requires additional development to make the protocols configurable per region. Since this is an open-source project, we highly encourage developers from North Macedonia to get involved. You are welcome to fork the repository or submit pull requests to implement support for the MK variants according to your local manufacturers' specifications, just as we have done for our local requirements.

do you know if i make a "local bridge" like a start up app and connect it to my website do i still need to send diferent information not this: {
"uniqueSaleNumber": "DT279013-0001-0000001",
"items": [
{
"text": "Cheese",
"quantity": 1,
"unitPrice": 12,
"taxGroup": 2
},
{
"type": "comment",
"text": "Additional comment to the cheese..."
},
{
"text": "Milk",
"quantity": 2,
"unitPrice": 10,
"taxGroup": 2,
"priceModifierValue": 10,
"priceModifierType": "discount-percent"
},
{
"type": "footer-comment",
"text": "YOU ARE WELCOME!"
}
],
"payments": [
{
"amount": 30,
"paymentType": "cash"
}
]
} that you are using?

To answer this question accurately, please provide the technical documentation for your specific fiscal device model, firmware version and its manufacturer. Without these specifications, any technical guidance provided would be unreliable.

As it seems you do not have developer background and knowledge, I would advise you to use a ready software and not implement (vibecode) things you do not understand, as the risk of getting hacked is real.

@g-vvv
I triedn it early this month but as a begginer i just gave information about dish price and quantity nothing else since i thought the fiscal would implement serial number etc..
After clickign print bill on my website button i got msg to the cmd that com3 sonnected sucessfully and the orders went through but as i said dish name,quantity and price nothign else,
And ofc it didnt print.

Daisy Perfect S Fiscal Printer
I used the official Daisy Tech serial protocol v1.8.1
The pc which restaurant has is 32bit windows 7 ..
My main concern still remains knowing the JSON based protocol for that.

@maslyankov That waiter panel where the print bill button is located is protected with email and password from firebase authentication .
Also for someone to hack and print bills they would need acces to the pc connected to the printer ..i dont see it happening.
Even though I admit I dont have any background in developing since im 1st year in university ...for as long as im informed hacking authentication directly from firebase with strict rules is not that easy...and after all who would want to hack a restaurant website when they cant get anything and can only mess with prices , photos...

You are free to ignore my advice...
You speak about firebase, yet you had been talking about connecting the fiscal service to the cloud, and that could very easily be a weak point. Especially when coding without understanding what you are doing.

As others have said, you are welcome to fork and improve the project with support for your fiscal device's protocol.

Regarding hacking, here is a lovely quote from Batman (the idea is there are people who scan the net for holes just to mess with people):

"Because some men aren't looking for anything logical, like money. They can't be bought, bullied, reasoned, or negotiated with. Some men just want to watch the world burn."

@maslyankov Appreciate it bro.

@21studiohd Review the ErpNet.FP service log for any error messages or connection issues. To interpret the log, please refer to the technical documentation I mentioned in my previous message.
