What are the requirements for printing 1 m * 1 m pictures of photographic works?

You can choose a large format photo printer instead of an inkjet printer. Both Epson and HP have 8-color large format printers. If you can find the best one that uses original ink and paper.

Because the picture of 1* 1 m is taken by Hasselblad H series, all other cameras should be cropped, and the pixels should be higher, preferably10.000 million pixels or more.
