Printronix MVP Series Option 20 Double Wide Print Operation Expanded Print Select, 150B/L150B

Option 20 — Double Wide Print Operation (Expanded Print Select)

Discussion

Option 20 makes it possible to print “double wide” characters. The term

“double wide” is related in an inverse manner to pitch, and generally alludes to the width of alphanumeric characters just before the double wide feature is invoked.

150B/L150B

Option	Display	Configuration
Number		Description
.0	20.0	Double wide on per line basis only. Enables Mode 6. Initiated by
		either control code ESC SO or SO (see page 7–31). If the printer is
		operating at 10 pitch when the control code is executed, printer
		operation shifts to pitch 5. However, if the printer is operating at
		16.7 pitch (Mode 5) when the control code is executed, printer
		operation changes to 10 pitch. If control code DC4 is received
		within that same line, it cancels any effect that ESC SO might have
		produced. See Note.
	20.1	Per character width doubling through control codes (Modes 1– 5)
.1
		but excludes bit image characters. Default. Disables Mode 6.
		See Note

NOTE: When executed, any one of the following codes causes the pitch to change by one–half: (1) SO, (TEXT), LF produces a line of double wide characters; (2) SO, (TEXT), DC4, LF produces a line at whatever pitch is in effect at the time the line is received; or, (3) ESC W CHR$ (1 or 49) will cause each succeeding line to have double wide characters.

Characters are produced at the reduced pitch until: the end of the line (printing takes place); a DC $ is received; or, in the case of ESC W n, an ESC W CHR$ (0 or 48) is received. Printing then resumes at the pitch rate in effect before the double wide feature was executed. For example, a line coded A (SO) B (DC4) C LF will be printed with “A” and “C” normal pitch and “B” double wide.
