The difference between thermal printer graphic printing and soft font printing

The thermal printer can select graphic printing and soft font printing in the device setting. If the graphic printer is used, the printer will print all the contents as pictures. If you use graphic printing, you can print the pictures and print the word art, as long as you can see it. I can print it out because he prints it all as a picture and prints it on paper like a photo. However, the soft font is different. The soft font printing converts the printed content into instruction printing. The printed font must be the font existing in the printer font chip. If you need to print the image, you need to use the command to create the raster bitmap. In short, all print content must be sent to the printer as an instruction. If you use a serial printer, you will find that printing in soft fonts is much faster than graphics printing, because the graphics print data flow is great! Even printing at the serial port baud rate of 115200 is still very slow, but if you use soft font printing, it will be quite fast, because the printed text is in the font chip, you can use these words through software control. . If you are using a USB printer, then choose the graphic printing method. The USB port has a high transfer rate, and the use of graphic printing is not affected by the large data stream. It is especially fast and easy to print. If you want to play anything, as long as you can see it, he will print it out for you.
