Automatic Recovery Function; Output Without Flow Control On The Usb/Ethernet Interfaces; Markfeed Function - Epson TM-L90 Series Development Manual

3.15 Automatic Recovery Function

The TM-L90 models feature a function for automatic recovery when the power is
turned on again after an interruption of power. Recovery processing is performed
automatically when the printer's power is turned on again after an interruption.
The recovery processing restores the printer to the condition it was in before the
power was turned off.

3.16 Output without Flow Control on the USB/Ethernet Interfaces

The TM-L90 models support outputting without flow control on the USB/Ethernet
interfaces.

3.17 MarkFeed Function

The TM-L90 models support the MarkFeed function.
The OPOS_E_ILLEGAL / OPOS_EX_INVALIDMODE is returned at the execution
of the PTR_MF_TO_CURRENT_TOF under the condition that the label is at the
peel-off position or the position other than cut position in the case of the "TM-L 90
with Peeler" model.
However, the OutputCompleteEvent is fired upon the processing of the
transferred command during the asynchronous print since the label position
cannot be comprehended.
The label peeling detector may not be able to detect paper if the TM-L90 with
Peeler is installed in a place where the printer is exposed to direct sunlight or
other strong light.
If PTR_MF_TO_TAKEUP is executed, the label is fed to the peeling position and
OPOS_E_OFFLNE/OPOS_EPTR_REMOVE_BUTTON is returned.
In this case, remove the label and then press the FEED button of the printer.
