I want to print an image on my receipt I am using EscPos.printImage(); . Could anyone please provide me a static image example of what exactly the file.uri should look like and what I have to pass in this function which will help me to print the image logo on top of the print.

I would be keen to know this too, I have tried using base64 string, url and imported image and non seem to work, I keep getting:

Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference.

Also @leesiongchan do you have a method for accepting donations, this module has saved us so much time on our current project we'd like to say thank you!

You can try https://github.com/leesiongchan/react-native-esc-pos/issues/24#issuecomment-558902168 to see if it work.

Hi thank you for your generosity, I must say that means a lot! However, I did this for one of my client projects, and the project is completed and I do not have a printer with me to help me further improve the library stability and adding new features. So I don't think I qualify to accept any donations since the quality of the project is not great and I simply can't contribute much on this project anymore.

We solved the problem we were having last night, for anyone else having the issue we just requested the external storage permissions and used the file:// path to the image in our case /sdcard/image.bmp in place of file.uri.

@leesiongchan you are very kind but this library has saved us a lot of time and effort so if there is a way to donate we would love to do so. We have forked it and are adding a load more markup options and characters to make it UK friendly as a few of the characters are missing in a lot of pos printers.
