Open `Printers & scanners` 15 | 2. Click `Add device` 16 | 3. Click `Add a new device manually` 17 | 4. Select `Add a printer using an IP address or hostname` 18 | 5. Select `IPP Device` as device type 19 | 6. Write `http://127.0.0.1:631/` or `https://127.0.0.1:631/` as `Hostname or IP address` 20 | 7. Click `Next` - You should successfully add printer. 21 | 8. Click "Print a test page" (optionally) 22 | 9. Click `Finish`. 23 | 24 | ### Windows (Script) 25 | 26 | ```powershell 27 | Add-Printer -Name "SharpIppNext" -PortName "http://127.0.0.1:631/SharpIppNext" -DriverName "Microsoft Print To PDF" 28 | ``` 29 | 30 | All steps are described in `Setup\Add-printer.ps1` 31 | 32 | ### Android 33 | 34 | Use the NetPrinter App. 35 | 36 | ## Requirements 37 | 38 | ASP.NET Core 8.0 Runtime needs to be installed. 39 | 40 | ## Integration testing (OpenSUSE) 41 | 42 | 1. Install package: `sudo zypper install cups-client cups-backends` 43 | 2. Obtain correct IP: `ip route` 44 | 3.
