Recoverable errors

Although normal printer operation is no longer possible when recoverable errors occur, they do
not represent printer failure. They are easily corrected through user actions and/or the use of
®
ESC/POS commands.

The DLE ENQ1 and DLE ENQ2 commands are enabled only when a recoverable error (excluding

condition that is the cause of the error and transfer the DLE ENQ1 or DLE ENQ2 command to
recover from the error without having to power down the printer.
