I'm working on flutter desktop app and i need to print invoice to USB printer.

Please help me solving this issues or suggest me some another solution or plugin.
Thanx.
Flutter desktop has been launched as stable earlier this year. Perhaps you may want to try running a desktop build again using the latest Flutter version. Simply run flutter upgrade to update the Flutter version that you're running on. Currently, the printing plugin is one of the stable printer plugins on Flutter.
If the issue persists, please include the logs from the app. This should give indicators if the app is able to communicate with the printer or if there's any issues with the document that you're trying to print.
I have an app for connection IoT devices. So when I open the app, my wifi hotspot must be automatically enabled. Can anyone suggest a way to this?
The wifi_iot package is probably the best you can get with Flutter for now. Their page on pub.dev specifically states what is possible right now.
wifi_iot will generate hotspot with random ssid li
I am developing an app for school project using flutter and it should have a feature of printing a PDF document over WI-Fi (using WI-FI printers).
I didn't find any tutorials on printing using flutter so I want to know if flutter supports such thing and if not, is there a way around it?
Thanks in advance
It looks like there is a printing package available for flutter here that might be what you need:

They even have example code that you can use:

Is there any way that I can print a receipt on a Bluetooth thermal printer, as I really struggling finding the solution on flutter? Anything could help, I really appreciate those answers
I have tried esc_pos_bluetooth package and it's not working for Bixolon bluetooth printer.
I'v found blue_thermal_printer library and it worked for me on Android but this library doesn't support iOS until now:
https://pub.dev/packages/blue_thermal_printer
Currently you need to write your own logic using Bluetooth packages.
There is package available which currently supports WiFi POS printer.
Take a look
https://pub.flutter-io.cn/packages/esc_pos_printer
Have you tried this package: esc_pos_bluetooth(https://github.com/andrey-ushakov/esc_pos_bluetooth)?
Not much luck on my end either (on ios). Unfortunately, esc_pos_bluetooth doesn't detect my Epson TM-T88VI so that's a little bit of a road block...
There are three major bluetooth printing plugins, i have tried them all and so far this package is the best one esc_pos_bluetooth is the best on my case.
Some useful Flutter SDKs for Thermal Printer:
bluetooth_thermal_printer - This is a Flutter plugin that allows you to use a Bluetooth thermal printer on Android device.
blue_print_pos - This is a Flutter plugin that enables you to use a
POS (point of sale) system on both Android and iOS device.
This is the updated forked blue_print_pos SDK which I used in Dec, 2022. You can use it without facing any issues.

I have installed the free version of smartface and just created a training project. When I build it my app install on virtual android device but I cannot see it. I just see the smartface adverts.
What can I do to solve this problem? Should I get it lisenced?
I didn't get your problem exactly, can you please share a screenshot?
And maybe you can check the link below for more information about Android virtual device usage :
http://www.smartface.io/developer/guides/project/virtual-devices-android/
By the way, you should create the virtual device using google api.
The screen that you mentioned is just shown at the beginning of the app for some seconds. Then you can see your application page and use it. You should reinstall it on a real android device.
