Hello,

I want to display an image in center of page, but not getting it displayed on center.
Kindly provide if someone got this working.
Thanks in advance.

Below is my code snippet.

void printOrder(queryParameters) async {
Map<String, dynamic> config = {};
List list = [];
list.add(LineText(type: LineText.TYPE_IMAGE, content: base64Image, align: LineText.ALIGN_CENTER, width: 200, height: 100, linefeed: 1));
list.add(LineText(linefeed: 1));
list.add(LineText(type: LineText.TYPE_TEXT, content: 'Token No.${tokenNo.text}', weight: 1, align: LineText.ALIGN_CENTER, linefeed: 1));
list.add(LineText(linefeed: 1));
list.add(LineText(type: LineText.TYPE_TEXT, content: 'Name: ${accountName.text} ${dateInput.text} ${queryParameters['orderTime']}', weight: 1, align: LineText.ALIGN_LEFT, linefeed: 1));
list.add(LineText(type: LineText.TYPE_TEXT, content: '--------------------------------', align: LineText.ALIGN_LEFT, linefeed: 1));
list.add(LineText(type: LineText.TYPE_TEXT, content: 'Item Qty Rate Amt', weight: 1, align: LineText.ALIGN_LEFT, linefeed: 1));
list.add(LineText(type: LineText.TYPE_TEXT, content: '--------------------------------', align: LineText.ALIGN_LEFT, linefeed: 1));
await bluetoothPrint.printReceipt(config, list);
}

Thanks!

@krunalagrawal i tried you code and it worked, the image was at the center. Here is what i think might be wrong:

1. Check the size of your image, the image i used was 226 x 290 and it worked.
2. Make sure there isn't extra spaces after your image

Hello @krunalagrawal

I’m reaching out to see if you’ve had any success with printing images on iOS using the bluetoothPrint method. Specifically, I’m trying to determine whether the issue you are facing is related to iOS or if it is unique to Android.

I am currently working on a project where I need to print images on iOS, but I’m experiencing difficulties. The images are not printing, and I would appreciate any insights or solutions you might have.
