Table 9: (Cont.) ESC / P2 Commands
Escape Sequence Function
ESC X P1 P2 P3 Select font by pitch and point
P1 = 0 : No change in pitch
P1 = 1 : Selects proportional spacing
P1 = 18, 24, 30, 36, 42, 48, 60 or 72
Selects fixed pitch equal to 360/m
cpi
pz = P2 + P3 x 256
pz: Point size in 0,5 points; 1 point
equals 1/72 inch
pz = 0: No change in point size
pz = 16, 20, 21, 24, 28, 32, 36, 40, 42,
44, 48, 52, 56, 60, 64
ESC ( U P1 P2 Set unit
P1 = 01 00
P2 = 10, 20, 30, 40, 50, 60 /3600"
P2 = 10; Standard
ESC c P1 P2 Set horizontal motion index (HMI)
Define HMI-Index
Change pitch value in n/360"-steps
HMI = P1 + P2 x 256
HMI max. 3 inch
