Upload the image, choose A4 and how many sheets you want, then download the PDF and print it at 100% scale. Each page carries crop marks and an overlap strip so the sheets line up when you tape them together.
Switch to "By finished size", type 1000 mm, and the tool works out the rows and columns for you — usually around 18 A4 sheets for a 1 m wide landscape image.
Almost always because the printer was set to "Fit to page". Choose "Actual size" or 100% instead. Also keep the overlap at 10 mm or more so you have something to trim and glue.
