[@UjangMisbah-i5u]

thank you very much the tutorial is very useful

[@La_bella_pizzaria]

good job man

[@ConadiaApp]

Hello, could you please help me, what happens is that the QR does not print completely, what can I do?

[@zainsoft8032]

Have you given permission to the printer Bluetooth access in your device?

[@ConadiaApp]

@@zainsoft8032 Yes, add the permissions in the manifest.

[@mouzinu]

Thanks, you helped a lot bro!

[@zainsoft8032]

You're welcome bro 😀

[@christianmorales6546]

Hello friend, what variables would you change if you have a different paper size? for example size 40x30mm

[@zainsoft8032]

The bluetooth mobile printer will adjust the character that we will print. If the first line is full, the text will go directly to the next line.

[@rafidalvi7585]

Sir Please help, App is not printing on some device. what to do ?

[@zainsoft8032]

Have you check app permission setting in your device? Connect to paired bluetooth devices must be allowed

[@rafidalvi7585]

@@zainsoft8032 tried that too. App only working on Xiaomi properly , not Working on Samsung

mas mau tanya kenapa waktu di coba sama printer zebra ga bisa ya?

[@zainsoft8032]

Bluetooth android dengan bluetooth printer zebra nya sudah terkoneksi belum? Kalau sudah nama printernya juga harus di daftarkan, seperti pada menit ke 10:35. Boleh di infokan type/jenis printernya mas?

[@erlanggasyabani4611]

@@zainsoft8032 printernya udah konek mas sama udah di daftarkan nama printernya.... tipe printernya zebra zd420 mas. mohon bantuannya

[@zainsoft8032]

Pada saat pendaftaran jenis printer pada menit 10:31, huruf besar atau kecil sangat pengaruh mas. Pada saat penghubungan android ke printer bluetooth 10:05, jenis printer harus sama dengan pada menit 10:31.

[@joaomarques1709]

I have an MTP-3 printer, won't it work?

[@zainsoft8032]

Yes, every Bluetooth printer will definitely work

[@joaosipro]

@@zainsoft8032 strange, mine didn't work, so I created a function so that once I generated the qrcode I could share it, then I shared it with the RawBT app, I even searched for the IP of the MTP-3 printer but still without success

[@joaosipro]

Do you think some function might be wrong, or my Blutooh permissions aren't working correctly?@@zainsoft8032

halo om. saya coba clone dari githubnya...terus ada error :Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with `checkPermission`) or explicitly handle a potential `SecurityException` ..... itu ada 5 pcs errornya. sama seperti itu di line 50,52,55,71,72 di bagian PrintBluetooth.java ...... mohon bantuannya om.... saya penasaran bgt buat bisa ngeprint lewat bluetooth.. terima kasih om

[@zainsoft8032]

Kalau errornya permission, coba cek di AndroidManifest.xml Apakah sudah sesuai seperti pada menit ke 04:23 ? Saat project nya di jalankan aplikasi tertampil di emulator atau tidak mas?

[@medicalrose1716]

@@zainsoft8032 udah om say cloning dari githubnya tanpa ada melakukan perubahan, bisa di install di emulator, juga bisa instal di hp. untuk bagian qr code berhasil jalan. tapi bagian print tidak ada respon printer nya. sudah sudah test pakai aplikasi lain di google playstore , printer berjalan normal..

Greetings from Peru, very good videos. I don't understand why the app can't print. I have reviewed each code and I can't find the error why it doesn't print 😥

[@zainsoft8032]

Have you given permission to the printer Bluetooth access in your android device? Previously, first connect the Android device with the Bluetooth printer (10:06) After that at minute 10:34, the printer name must be the same as the bluetooth printer name at minute 10:06 Good luck

[@jcayournewstyle182]

@@zainsoft8032 Yes, that is true, everything is correct, but it is very strange that it does not print. I'm looking for the reasons, can I send you the activity? How much do you charge me to solve this? I am a businessman but I like to learn android studio is a very nice but complicated world at times.

[@barkadazzz2556]

why i print out special character instead of qrcode?

[@zainsoft8032]

Sorry, i haven't tried it 🙏

@@zainsoft8032 i mean, why it doesn't print QRcode. i use the same code in your tutorial to take as knowledge to me. instead of printing QRCODE it will print special character

@@zainsoft8032 makasi mas. mas mau tanya untuk video ini saya ada kendala di menit 8:00. yang dimana saat saya ketik printBT dia gamau muncul. ada solusinya mas? atau mungkin ada discord atau telegram untuk tempat berdiskusi?

[@zainsoft8032]

Ooo, maaf mas, mungkin ke edit saya bagian itu. berarti kelas PrinterBluetooth.java belum dipanggil. samain aja mas sama seperti menit 2:30. EditText inQRCode,in_printer_id; TextView buttonCreateQR,button_print; ImageView imageQR; PrintBluetooth printBT = new PrintBluetooth(); //ini script untuk memanggil kelas PrinterBluetooth.java insya Allah langsung hilang errornya. :)

[@ragulsithuraj9929]

Hi bro, It is really helpful. Can we use any Bluetooth printer to connect this app? If so, which printer is best for this?

[@zainsoft8032]

Yes, all bluetooth printee can be used. In indonesia We use RPP02N, because it's easy to get and cheap.

you can check in minutes 06:27. in method CreateQRActivity.java, line 62. you can change the size 300. Example: BitMatrix bitMatrix = multiFormatWriter.encode(textToQR, BarcodeFormat.QR_CODE, 400,400);
