Chapter 5 Configuring the Proprinter III XL Emulation with Control Codes

Select Proportional Spacing

ASCII Code ESC P n

Hex Code

1B 50 n

 

Dec Code

27 80 n

 

Purpose

Enables/disables proportional spacing of characters.

where:

n = 1, 3, 5

...(any odd value) enables proportional spacing

 

n = 0, 2, 4

...(any even value) disables proportional spacing

Comment

This command is ignored when a non-proportional font is used.

Superscript/Subscript Printing

ASCII Code ESC S n

Hex Code

1B 53 n

Dec Code

27 83 n

Purpose

Selects superscript or subscript printing.

where:

if n = 0, 2, 4... (any even value) superscript printing is enabled

 

if n = 1, 3, 5... (any odd value) subscript printing is enabled

Comment

Superscript/Subscript font prints at one-half the normal vertical

 

character height and at twice the normal vertical density. When

 

the superscript/subscript control code is received, all characters

 

are superscript or subscript until reset by the superscript/

 

subscript reset control code or printer reset. Emphasized print is

 

ignored in the superscript/subscript print mode.

 

Both superscript and subscript characters can be printed in the

 

same character column using the Backspace (BS) control code

 

(page 118).

 

Caution should be used when combining Superscript or

 

Subscript printing with other print attributes such as Elongated

 

(Double High), or small line spacing; overlapping lines may

 

occur. Characters with different horizontal or vertical dot

 

densities do not overlap.

Example

The following sample illustrates superscript/subscript printing.
