Backspace (BS)
BS (hexadecimal 08, decimal 8)  moves the cursor left by the
width of the last printed character or space. With fixed-pitch
fonts, the backspace distance is the current Horizontal Motion
Index (HMI). With proportionally-spaced fonts, a single
backspace centres the new character over the character to the
left. When multiple backspaces are used, each backspace moves
back by the width of the last character printed, regardless of the
width of the character being backspaced over. 
Horizontal Tab (HT)
HT (hexadecimal 09, decimal 9) moves the cursor to the next tab
position on the row.  Tab positions are defined at the left margin
and every eight columns thereafter. 
Line Feed (LF)
LF (hexadecimal 0A, decimal 10) moves the cursor down one row
within the same column.  The height of the row is defined by the
current Vertical Motion Index (VMI) which has been set by a VMI
or a Line Spacing command. 
Form Feed (FF)
FF (hexadecimal 0C, decimal 12) moves the cursor to the same
column on the top line of the next page.
Font commands
When you select a font, the 4213 printer searches its memory for
one that most closely matches your choice.  The printer selects
the “best fit” according to eleven font characteristics, in order of
importance:
Symbol set
Spacing
Pitch
