Epson TM L90 Technical Reference Manual page 70

If you use the printer without making a layout setting and a paper out (no paper left) or an error
occurs as a result (refer to page F-3), opening and closing the cover automatically sets a new
layout.
Note:
The above automatic layout setting by opening and closing the cover is available with firmware
version 1.05 or later. It enables you to make layout setting by intentionally generating an error in
paper feeding on printing. This function can be turned off using the memory switch setup utility.
Automatic paper layout setting
Automatic paper layout setting sets a paper layout on the basis of the black mark or label
position detected by the printer.
This method is available for label paper, receipt paper, and receipt paper with black mark.
Note:
When using label paper with black mark, it is necessary to make manual setting of paper layout (set using
the memory switch setup utility or ESC/POS command).
This automatic paper layout setting can be used with any of the following three methods.
• Use the automatic paper layout setting mode provided for the printer.
• Use the memory switch setup utility.
• Directly control the printer using ESC/POS commands.
Note:
For the memory switch setup utility and ESC/POS commands, refer to "Introduction of Control
Methods" on page 4-1.
When using Advanced Printer Driver (APD) or ESC/POS commands, set the print area as required. The
print area position influences the paper layout.
Described below is a procedure for automatic setting of paper layout that allows you to
independently set the paper layout on the printer.
It is also possible to cause an error intentionally so that the printer will feed several labels and
remember the label paper size. See the instructions below.
