C # print memory

The following instances can be copied and used directly.

Overall idea: Save the print settings to a local file, read the file information directly at the next printing, and get the value through serialization and deserialization. In this example, only horizontal and vertical settings are set for printing. You can also add other settings to save and read them. Main method memoryprint
