Elongated (Double High) Print, Set/Reset

ASCII Code ESC w n

Hex Code	1B 77 n
Dec Code	27 119 n
Purpose	Turns double-high character printing on and off. Double-high
	characters are standard width but twice as high.
where:	n = hex 1 or hex 31 turns double high printing on
	n = hex 0 or hex 30 turns double high printing off
Comment	The OCR A and OCR B fonts cannot be printed in double high.

NOTE: It is recommended to use double Line Feeds and Carriage Returns when double-high character printing is on (after an ESC w control code has been sent), or else the printer overstrikes text that has already printed.

If Superscript/Subscript (ESC S) or Condensed Print (SI) is combined with Double High printing, only Double High printing occurs.

Example The following sample illustrates double-high character printing.

Emphasized Print

ASCII Code ESC E

Hex Code	1B 45
Dec Code	27 69
Purpose	Selects emphasized character print format.
Comment	When the emphasized print control code is received, all
	characters are printed in emphasized print until reset by the
	emphasized print reset control code or printer reset.
	Emphasized print is ignored during superscript or subscript
	printing, and when 15-20 cpi characters have been selected.
Example	The following sample illustrates emphasized character printing.
