CHAPTER 4. PRINTRONIX P-SERIES EMULATION
SPECIAL FUNCTION CONTROL CHARACTER (SFCC)
When a printer control code consists of more than one character, it is
called a command or escape sequence. This emulation uses a Special
Function Control Character (SFCC) as the first character of a
command sequence. The SFCC alerts the printer that a command
sequence—not printable characters follows.
▪ In this P-Series emulation mode, you may choose 0 to 127 to be
the SFCC via the Emulation Settings of the Set Up Menu.
The general format for a command sequence in the P-Series
emulation is:
SFCC (parameter 1 ..... parameter n) (terminator)
Command Line
In the P-Series emulation mode, print format, font, or international
language selection can also be controlled by a longer sequence known
as a Command Line. Command Lines are string type commands
placed between complete lines of text and affecting the text that
follows. The P-Series Emulation has six Command Lines: PMODE,
OSET, PSET, LPI, LINES, and INCHES. Each of these Command
Lines is discussed in this chapter under the appropriate Control Code
function.
For example, you can set the form length in inches by using the
following command line:
SFCC INCHES ; n f
where n is the whole number of inches and f is the fractional
increment in 0.5 inch increments.
When using the SFCC in a Command Line, it must be the first
non-blank symbol in the line (space, hex 20, is a blank symbol).
In addition, characters following spaces (other than a valid line
terminator) in a Command Line are ignored so that user comments
can be included on the Command Line. The valid line terminators are
Form Feed (FF), Line Feed (LF), and Carriage Return (CR); however,
when used in the Command Line, these line terminators do not cause
any paper motion.
