jsprintmanager-blazor's Issues

Feeder Scan Not Working

While testing JSPM out, I found that printing and flatbed scanning seem to work fine, but when I check the 'Enable Feeder' checkbox (also tried on the demo page) it still scans from the flatbed. I played around with the Feeder Count (including values 0, 1, 50), but no difference.

Here is an image with the settings I tried

To make sure the feeder on my printer works, I did several successful feeder scans from the 'Scan' app on the same computer as in the previous tests.

My Specs:
OS: Windows 11 Pro Version: 22H2
Sofware: jspm5-5.0.22.801-win32.exe (32-bit version of JSPM for Windows)
Printer: Brother DCP-7065DN (It has a feeder)
License: NONE

JSPPrintmanager not working with .Net 6

Hello

I want to test the JSPrintmanager in my Application but actually I am using already .Net 6. The Websocket Connection was working fine but when I want to print a File, I get an error in my Console which is called:

Uncaught (in promise) Error trying to decode the base64 data.
InvalidCharacterError: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

So i tested it with a empty Blazor project in .Net 5 and .Net 6 and the problem happened only in the .Net 6 project.
So is the JSPrintmanager already released for .Net6 and if not when is the release planned?

Regards Samuel
