The "f" at the end of the escape sequence represents the final character. It terminates
the sequence, and specifies the function to be performed.
Spaces are used when documenting escape sequences to increase readability. The
spaces within the sequences are for readability only; they are not part of the
sequences themselves. Characters that appear in italics (such as "n" and "f" above)
are not sent to the printer as is; they are used as a place holder indicating that some
value must be supplied.
Multiple character strings without intervening spaces typically represent control
codes. For example, BS is the Backspace control code (08 hex), not the two
characters "B" and "S" (42 and 53 hex). An ASCII Control Code Table is contained
in the appendices for your convenience. If you have any doubt about how to interpret
a documented control code or escape sequence, refer to the hex representation in the
provided example. This should clarify any ambiguity. The examples may also be
helpful when analyzing a hex dump (see chapter 8) printed by the printer.
Some escape sequences refer to the active column or active line. The active column
is the column where the next character will be printed. Printing a character or a space
will increment the active column. The active line is the line where the next character
will be printed. A line feed will increment the active line. Column and line numbers
begin at one, not at zero. Keep this in mind when setting tabs, margins, etc.
