print_diag: this tool sends to a given printer (or other IPP endpoint) Get-Printer-Attributes request and returns the received response. The response is parsed and can be saved both as JSON file or as a raw binary file. This tool allows also to choose an IPP version used in exchange. Run the program with --help parameter to get more details.
