Error: "could not open IPC socket (No such file or directory)" one time when a printer is connected #9

When a printer is just connected an info/status request sometimes returns an error once. The second time it returns success with printerstate set to idle.

This seems be caused by a moment where printDriver.getPrinter() returns "3D-printer[ttyACM0]" instead of nil. But then printer:getState() returns "nil" with the message "could not open IPC socket (No such file or directory)". On the second request the rinter:getState() returns "idle"

Summary:

  1. Not connected: printDriver.getPrinter() > nil
  2. Connected: printDriver.getPrinter() > "3D-printer[ttyACM0]" printer:getState() > nil error response: "could not open IPC socket (No such file or directory)"
  3. Still connected: printDriver.getPrinter() > "3D-printer[ttyACM0]" printer:getState() > "idle"

It's as if print3D is running but the socket needs a bit more time to start.

In the current the client printer.state is "unkown" for a moment, which we ignore.

I'm not sure this was solved.
