[Outline] This command prints the data in the print buffer and feeds the paper by n/60 inch in the reverse
direction. Since the printer has the minimum paper feed pitch of 1/144 inch, n/60-inch reverse
directional paper feed is treated as follows:
• For the standard mode: The paper is fed by an approximate value of INT((6n+5)+0.5)/72
inch.
[Caution] • The command is valid only in the standard mode.
• The head of the line is assumed to be the next printing start position.
• A set amount does not remain.
