§ The Large characters are formed by using a 10x14 dot matrix. Large character print is
selected if both Expanded and Extended print is selected. To reset large print to normal
print, Expanded and Extended prints must be disabled or Carriage return sent to printer.
Dot Addressable Graphics
§ The SERIES 2000i can print special symbols, graphs and characters if operated in the
Dot Addressable Graphics mode.
§ In the Dot Addressable Graphics mode of operation, the printer prints one dot line at a
time. Each horizontal dot line is made out of (1x6) dot cells, and the total number of dot
cells per line is the same as the maximum number of columns on the printer.
§ Each dot in a (1x6) dot cell can be turned ON or OFF by sending specific ASCII
characters.
§ The graphics mode is invoked by sending ASCII characters 'ESC' (1B/27) followed by
'G'. Dot line printing starts upon receiving enough dot cells to complete a dot line, or
ASCII 'CR' (0DH) or ASCII 'LF' (0AH)
§ The graphics mode is terminated by sending ASCII characters 'ESC', followed by 'A'.
Graphic Character Set
§ The graphic character set extends from the character '?'(3FH) to TILDA (7EH). Bits 1
through 6 of the characters received are used to turn ON or OFF the dots in a dot cell.
§ If a bit is set (=1), a dot is enabled, otherwise the dot is disabled.
§ For example for ASCII '?' (3FH or 00111111B), bits 1 through 6 are set. Sending
consecutive '?'s will form a one dot solid line across the paper.
