I do not understand how to print from an application running inside the GSPlus emulator. For example, there are no error messages that result from printing text from within the 'Teach' application, but I have no clue as to where said text is 'printed'. By contrast, it is possible to print a text file from inside an application within the AppleWin emulator to a file named 'printer'txt' located in the folder in which the AppleWin.exe file resides.
While GSPlus does allow capturing a screen to a file via the 'F3' key, I cannot determine how to get GSPlus to 'print' to a file in a manner similar to how AppleWin does.
Any insight into how to address this issue is sincerely appreciated.
GSPlus doesn't have this capability. Try GSPort: https://david-schmidt.github.io/gsport/
