Device enabled checkbox: If checked, the virtual HP-IL generic printer is available and can be used as HP-IL device. The HP-IL loop must always be reconfigured after activation or deactivation.

Enabling or disabling devices in pyILPER is like adding or removing devices from a HP-IL loop which needs a reconfiguration of the HP-IL controller. Otherwise a new device will not be accessible. To reconfigure the loop switch the HP-41 off and on.

With the (real) HP-41, a calculator off/on is usually not needed, since the 41 reconfigures the loop at each operation (except with advanced modes of the X-I/O module). This can be checked with the scope display (AAU, AAD 1 sequence). This was designed in this way intentionally to make the HP41 HP-IL works mostly automatically without user actions, at the expense of redundant HP-IL traffic.
With the HP-71B, yes an off/on cycle or a RESTORE IO is needed.
