To ease reading the recipe while cooking, the M5Paper hangs on the cooker hood (my fridge is not magnetic unfortunately) and shows the recipe's details on its ePaper display.

All recipes are managed in the Recipe Keeper app, and the information about ingredients and preparation is sent via Telegram API to M5Paper.

Solved, this works fine:

char Rezept[50] = "Line 1 \n Line 2";

and

canvas.print(Rezept);

I am trying to display a longer text received from Telegram on the M5Paper display. The text includes \n for line breaks, however I am unable to display it properly. This is the snippit from the Arduino code:

String Rezept = "Line 1 \n Line 2";

void setup() {
Serial.begin(115200);
M5.begin();
M5.EPD.SetRotation(90);
M5.EPD.Clear(true);

canvas.createCanvas(540, 960);
canvas.setTextSize(3);
canvas.setTextArea(0, 0, 760, 390);
canvas.setTextWrap(true, false);
canvas.printf(Rezept, 35, 350);
canvas.printf("Line 1 \n Line 2", 35, 350);
canvas.drawString("Line 1 \n Line 2", 35, 350);
canvas.pushCanvas(0,0,UPDATE_MODE_DU4);

I tried different methods, but none works:
canvas.printf(Rezept, 35, 350); --> no matching function for call to 'M5EPD_Canvas::println(String&, int, int)'
canvas.printf("Line 1 \n Line 2", 35, 350); --> This works well, but I hard coded text
canvas.drawString("Line 1 \n Line 2", 35, 350); --> does not recognize the \n

Any idea what I can do? Thanks a lot!
