| |
| ## printer_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. |
| |
| `printer_diag` is included in every ChromeOS image but you can access it only |
| in development mode. It may be run on the device from the console level: |
| |
| ``` |
| printer_diag --url "ipp://example.org/printer" --version=2.0 --jsonf=out.json --binary=out.raw |
| ``` |
| |
| In this example, the IPP Get-Printer-Attributes request is sent to the given |
| URL. The version of IPP protocol is set to 2.0 (default is 1.1). Obtained |
| response is dumped to a binary file out.raw (optional). The response is also |
| parsed and saved in JSON format to a file out.json (optional). |
| |
| Run the program with `--help` parameter to get more details. |
