@@MrNawshad my android terminal has an incorporated printer but when i try your code by specifiying the ip adress and the port i get : connection refused, please what can i do ???
@@mestutosisptheophile8991 I guess your terminal printer does not have an associated ip address, the ip address you are targeting is for the terminal itself. I think you have to print to this printer through USB communication. if you look into the terminal's manual they usually proved with printer sample code. thanks.

hi i made webview i want to print that using android print manager on print preview page the webview contains white border at all place how to remove
Can I use the same method Print() for printing an image instead of IList
Why you made a class in each platform with the same implementation ?
Why you didn't make just one class at the shared project and call the print() function from the button ?
to show the use of dependency service. You could use the same code on the shared project and that would work the same way. Thanks

Make sure you target the right IP address of your printer.

You need to configure the printer on your network.
