Character Attributes (SGR)
Character attributes are enhancements that let you highlight your printed text.
You can select ten character attributes by using Select Graphic Rendition
(SGR) sequences:
• Select font (DEC multinational character set, NLQ, OCR–A, OCR–B)
• Character Expansion via Graphic Size Modification (GSM) sequences
(Double height characters, triple height characters, double width
characters), if the font was selected by family.
• Select Graphic Rendition (Bold, Italics, Underline, Strike through)
Character attribute sequences share the same basic format as the select font
sequence. This type of sequence is called a Select Graphic Rendition (SGR)
sequence:
ESC [ Ps m
You can select more than one character attribute in the same sequence by
including several Ps values separated by semicolons:
ESC [ Ps ; Ps ; Ps m
Once set, a character attribute remains active until you turn it off or reset the
printer.
Ps = 0 (zero) turns off all character attributes.
