Print position
The print position is the standard position for printing characters, bitmaps and bar codes.
With the print position, there is a horizontal print position, which is the reference point for
vertical position movement.
Each character is arranged so that their top edge aligns with the print position.
The baseline of each character is the bottom edge of the character, regardless of size, font,
etc.
All characters on the same line are printed so that the baseline position is the same for
each character.
If the text consists of characters with different heights, the characters are aligned on the
baseline of the tallest character in the line of text.
In addition, underlines are printed 4 dots below the baseline position.
Bitmaps, bar codes and transferred images
These types of image data are treated in the same way as characters and are printed so
that the bottom edge of the image aligns with the baseline.
Same line
・Horizontal movement to the right between characters or images is regarded as being on
the same line; however, movement to the left is regarded as being on different lines if text
wrapping occurs.
