add some funcs for setting the name of printers from your code.

[Hurumy]

Summary

Now you can set the names of printers to be scanned from your code, just using member functions.

Added private member of a CatPrinter class:

NAME_ARRAY_SIZE = 6;

Setting the max size of char* array of printer_names.

NAME_STRING_SIZE = 8;

Setting the max size of each name.

printer_names[NAME_ARRAY_SIZE][NAME_STRING_SIZE];

Reserve memory for array of names.
Indicates the end of the array with an empty string instead of NULL.
When you call the constructor of CatPrinter, this name array has default value: GT01, GB01, GB02, MX09
So you can use both new and old codes without any fixing.

Added public member of a CatPrinter class:

void resetNameArray(void);

Remove all value of printer_names.
Replace each value with empty string.

bool addNameArray(char *newname);

Add newname to the printer_names.
If the array is already fulfilled, it returns false.

void printNameArray(void);

Print the values of printer_names by Serial.println. It maybe useful for debugging.

Other fixing

Moving the implementation of the constructor

I moved the implementation of the constructor from header to .cpp, because the definition of printer_names is done below of this function.

Add these funcs to the print_demo.ino file

Users can easily find a way to set the names of catty printers to be scanned.




Thank you for your impressive work!!

Thank you very much for your contribution. Could you please fix the issue with the array initaliziation?

Good morning. I fixed the issue and tested, then it worked.
How about this!
