Print resolution is measured in DPI, ie. dots per cm² To put it simply, we have the following image, for example, in a resolution of 650x400 (really small, only 260000points) when printing 300DPI we get about 17x10cm readable image without significant squares (dots). At lower DPI, individual points begin to appear. At a large magnification to the size you require, the image would gradually begin to decompose into individual points. As a preview of the higher magnification, reduce the print setting to a lower DPI. while maintaining the same size of the printed image. As a small example, this might be enough. You can try it without printing on a monitor. For example, enlarge the sample image to the entire area of the monitor, you will see individual pixels - pixels and you only have a small magnification (2-5 times depending on your set monitor resolution) Now think if you want a really realistic photo, with all the necessary shades (normal the printer manages 256 shades, don't believe the advertising bombs of 65 million colors and the like), 1 - in the positive case you will have to turn to a specialized printer, where they can produce poster wallpaper on the plotter (large-scale printing). 2 - If you want a simplified, square-styled image, the art has different forms, you are able to handle it on a regular color printer (high cost) on your chosen paper. There are no limits to artistic creation, apart from the well-known lack of money, space, peace at work and envy of enemies. All you need is the right view, the beautiful justification of the point, when even a lack or mistake can be considered an artistic intention. And especially not to be afraid to express your artistic opinion.
