Request for Help: Implementing or Using This Project in an Android Kotlin App

[MaretArt]

Hi everyone,

I'm currently working on an Android application using Kotlin and I need some assistance with implementing or using this project in my app. It is important to note that I have very limited knowledge of TypeScript and almost no experience with it.

Could anyone with experience in both TypeScript and Kotlin help guide me through this process? Any advice, examples, or resources would be greatly appreciated.

Thank you in advance for your support!

It depends on your needs. If you you only need to embed this app to your app, you can use webview (Capacitor for example). Otherwise you need to port niimbluelib to desired language.

Maybe this project code can help you somehow (first option): https://github.com/dotnetdreamer/capacitor-niimbot-printer

[MaretArt]

Tergantung pada kebutuhan Anda. Jika Anda hanya perlu menyematkan aplikasi ini ke aplikasi Anda, Anda dapat menggunakan Capacitor. Jika tidak, Anda perlu memindahkan niimbluelib ke bahasa yang diinginkan.

Mungkin kode proyek ini dapat membantu Anda: https://github.com/dotnetdreamer/capacitor-niimbot-printer

I really appreciate your reply and feedback, but what I need is the second option. Do you have any suggestions or anything to port nimbluelib to kotlin?

[MaretArt]

I have tried several times, but it only works for Niimbot B21. I want it to work, for Niimbot B21 and B1. Can you help me a little?
If you are willing, I will attach a snippet of my code.
thanks a lot

There is a port of niimprint to Kotlin, I think you can extend it or use it as a starting point https://github.com/terratempest/android_niimprint

Sure

B1 and B21 has differences in print sequence.

See this page: https://multimote.github.io/niimbluelib/documents/NIIMBOT_print_tasks.html

[MaretArt]

Saya sudah mencobanya beberapa kali, tetapi hanya berfungsi untuk Niimbot B21. Saya ingin ini berfungsi untuk Niimbot B21 dan B1. Bisakah Anda membantu saya sedikit? Jika Anda bersedia, saya akan melampirkan cuplikan kode saya. Terima kasih banyak

Tentu

thank you, this is what i have tried

B1 and B21 has differences in print sequence.

See this page: https://multimote.github.io/niimbluelib/documents/NIIMBOT_print_tasks.html

thanks,
i have tried to fix it, but when i try to print, it doesn't print anything.
after i try to see the printer response, i see something that i think or maybe it's a mistake when i set the page size, here is the response:

[85, 85, 20, 2, 1, 0, 23, -86, -86]

is that normal? shouldn't the response be the same on index 2 and 5, that is 20 or 0x14?

[MultiMote]

is that normal?

Yes. Check the real B1 exchange: AndBondStyle/niimprint#31 (comment)
List of request and response codes: https://multimote.github.io/niimbluelib/documents/NIIMBOT_printers_protocol.html#md:list-of-packets

allowPrintClear()

Not needed for B1.

while (!endPagePrint())
delay(50)

For B1 you need to send only single PageEnd.

private suspend fun startPrint(): Boolean {
    val resp = sendCommand(0x01.toByte(), byteArrayOf(0x01.toByte()))
    return resp[4] != 0.toByte()    // i: 2 or 5, res: 0x02 or 2
}

That's not correct for B1. You should use this format (7 data bytes): https://github.com/MultiMote/niimbluelib/blob/19c3072d135eb53b1ff198ab8771a164583bf8bf/src/packets/packet_generator.ts#L168-L170

@MultiMote I am very grateful for your input and direction. Overall I have successfully printed using both types of printers (B21 and B1) but when I print on the B1 printer the results shift to the right.
This is the code I use to encode the image:

fun encode(image: Bitmap, printDirection: PrintDirection) : EncodedImage {
    val rowsData = ArrayList<ImageRow>()
    var width = image.width
    var height = image.height
    if (printDirection == PrintDirection.LEFT) {
        width = image.height
        height = image.width
    }

    if (width % 8 != 0)
        throw IllegalArgumentException("Column count must be multiple of 8")

    for (y in 0 until height) {
        var isVoid = true
        var blackPixelCount = 0
        val rowData = ByteArray(width / 8)
        for (x in 0 until (width / 8)) {
            var pixel = 0
            for (bit in 0 until 8) {
                var current = image.getPixel(x * 8 + bit, y)
                if (printDirection == PrintDirection.LEFT)
                    current = image.getPixel(y, x * 8 + bit)

                val r = Color.red(current)
                val g = Color.green(current)
                val b = Color.blue(current)
                if (r != 255 && g != 255 && b != 255) {
                    pixel = pixel or (1 shl (7 - bit))
                    isVoid = false
                    blackPixelCount++
                }
            }

            rowData[x] = pixel.toByte()
        }

        val newPart = ImageRow(
            type = if (isVoid) "void" else "pixels",
            rowNumber = y,
            repeat = 1,
            blackPixelsCount = blackPixelCount,
            rowData = if (isVoid) null else rowData
        )

        if (rowsData.isEmpty())
            rowsData.add(newPart)
        else {
            val lastPacket = rowsData.last()
            var same = newPart.type == lastPacket.type
            if (same && newPart.type == "pixels")
                same = newPart.rowData!!.contentEquals(lastPacket.rowData)

            if (same)
                lastPacket.repeat++
            else
                rowsData.add(newPart)

            if (y % 200 == 199) {
                rowsData.add(
                    ImageRow(
                        type = "check",
                        rowNumber = y,
                        repeat = 0,
                        blackPixelsCount = 0,
                        rowData = null
                    )
                )
            }
        }
    }

    return EncodedImage(width, height, rowsData)
}

and this is the print result:

I reconstructed your print from packets and it looks like this:

Maybe you need to change your print direction.

BTW, your original image is too big for B1 (this printer has 384 pixels printhead). Are you scaling it down before processing?

[MaretArt]

@MultiMote wow, awesome
i didn't realize that width and height in SET_DIMENSION were swapped.

thanks a lot @MultiMote for everything, now it works normally

Saya merekonstruksi cetakan Anda dari paket-paket dan hasilnya seperti ini:

Mungkin Anda perlu mengubah arah cetak Anda.

BTW, gambar asli Anda terlalu besar untuk B1 (printer ini memiliki printhead 384 piksel). Apakah Anda mengecilkannya sebelum memproses?

on SET_DIMENSION my width and height are swapped. that's all

[MaretArt]

@MultiMote Oh yeah there's more, how do you know the size of paper used in the printer?
like this:

[MultiMote]

1. Send RfidInfo and parse the result.
2. Make HTTP query using barcode from RfidInfo and read dimensions from the result

POST https://print.niimbot.com/api/template/getCloudTemplateByOneCode HTTP/1.1
Content-Type: application/json
niimbot-user-agent: AppVersionName/999.0.0

{ "oneCode" : "LABEL_BARCODE" }

There is no offline way of doing this known to me.
