PrintAsync Function Bug

[clayzzzzzzzzzz]

Description
If the printer name contains Chinese or full width spaces, the PrintAsync function will fail.
Here is my code:
CoreWebView2PrintSettings printSettings = webView.CoreWebView2.Environment.CreatePrintSettings();
printSettings.PrinterName = "HP LaserJet 400 M401 PCL6 Class Driver(副本1)";
CoreWebView2PrintStatus printStatus = await webView.CoreWebView2.PrintAsync(printSettings);
printStatus will be OtherError.

Version
SDK: Microsoft.Web.WebView2 v1.0.1722.32
Runtime: C# .NET Framework 4.6.1
Framework: WinForms
OS: Win10

Yes!
When i rename this printer to ”HP LaserJet 400 M401 PCL6 Class Driver()“ and “HP LaserJet 400 M401 PCL6 Class Driver”，webview2(v1.0.1722.32) will always print successfully.

Hi @monica-ch customer reports the issue still exists in version 1.0.1774.30, so I reopened the issue. May you take another look?

[monica-ch]

@clayzzzzzzzzzz Sorry you are seeing the issue again. May I know the WV2 runtime version installed on your machine?

Also, I believe printer name is either of HP LaserJet 400 M401 PCL6 Class Driver()/HP LaserJet 400 M401 PCL6 Class Driver right?

@monica-ch The WebView2 Runtime version is 114.0.1823.43
If the printer name is LaserJet 400 M401 PCL6 Class Driver() or HP LaserJet 400 M401 PCL6 Class Driver, it will print correctly. If the printer name contains Chinese, it will fail to print.
In addition, Some users name the printer based on its location, so there is a high possibility that printers may include Chinese characters in China.

@clayzzzzzzzzzz Yes able to repro it locally if printer name has Chinese characters. We are actively working on the fix and update the thread once we fix is in. Thanks!

@clayzzzzzzzzzz This should be fixed in runtimes 116.0.1932.0+. Thanks!

Hi, @monica-ch.

I would like to know how to upgrade webview2 runtime, I upgraded webview2 from 1.0.1774.30 to 1.0.1905-prerelease in Nuget, but the runtime was still 114.0.1823.43.

[monica-ch]

@clayzzzzzzzzzz You can use Edge canary channel for testing as the fix is not in the stable runtime yet. Please refer Testing upcoming APIs doc for more info.
