This image is 800 pixels wide, and has a pixel density (DPI) of 72. I have the rulers set to inches, so 800 ÷ 72 = 11.11 which is reflected in the ruler. The image will print at 11 inches with these settings. However 72DPI would not make a good print, and we tend to think of 300DPI as optimum. So if I change the DPI to 300, but uncheck
The following example will print the first field (line 1) at 150 dpi and the second (line 2) at 300 dpi: ^XA ^MUd,150,300 ^FT200,100^A0I,50,50^FDline 1^FS ^MUd,300,300 ^FT200,150^A0I,50,50^FDline 2^FS ^PQ1 ^XZ. In case it is needed to print all the text field with a lower resolution, the code must be modified as the following: A 200 dpi print means that for each inch of that printed material, it takes about 200 dots to make the picture. Thus, a ‘high dpi’ image means that it has so many dots tightly printed together with less space between them than a ‘low dpi’ image. Images with high dpi value appear sharper and colors appear to blend better Moving past image quality differences between 203 and 300 DPI, there is another, more relevant reason for our industry to invest in a higher resolution print head. A 300 DPI print head allows more information to fit into a smaller barcode. Simply put, you can print a smaller barcode containing the same amount of data.
DPI is dots/pixels per inch. In most commercial film scanners, the scan size is often given as a DPI of a print size. So in your case if they really gave you 300 DPI then at the pixel resolution of the files you received, the print size would be 3.3x4.2 inches. So uhhh you got 2.4 MP scans which is pretty crap and well, useless for printing
