The values for n1 and n2 are two bytes in low byte, high byte word orientation.
Determine the value of n by multiplying the number of columns to move left of the current
position by 10 (standard pitch) or 8 (compressed pitch). The example shows how to set the
relative position two columns in standard pitch (10 dots per column) to the left of the
current position.
Align Positions (Receipt Station)
Specifies the alignment of the characters, graphics, logos, and bar codes on the receipt
station according to the table below. The command is valid only when input at the

Select Paper-End Signal Output
This command is not implemented and is ignored if received. The four bytes of this
command are used for backward compatibility to Epson TM-930™ applications. The RS-
232C interface can accept multiple status bits, unlike the parallel interface (used in the
Epson TM-930™).

affect the paper out sensor on the receipt station which automatically stops the printer
when the paper runs out.
