ALL INITIALIZE
A
Places the printer in the text mode.
HOME (PHONE) H Lifts the pen and returns it to the origin (home
position).

y=O).
DRAW (LINE) Dx, y, ... , xn, yn
Draws lines from the current pen location to
(-
999~x, y~999)
coordinates (Xl. Yt), then to coordinates (X2, Y2),
and so forth.
RE LA TIVE DRAW
J.:lx, .:ly, ... , .:lxn, .:lyn Draws lines from the current pen location to reI a-

dinates (.:lx2, .:lY2) and so forth.
MOVE (MOVE)
Mx, Y
Lifts the pen and moves it to coordinates (x, y).
(-999~x, y~999)

3)
Specifies the direction in which characters are
printed.
PRINT PCtC2C3 ... cn (n =
00)
Prints characters.
AXIS (AXIS) Xp, q, r (p=O or I) Draws an X axis when p = I and a Y axis when
(q = - 999 to 999) p = O. q specifies the scale pitch and r specifies the
(r = I to 255) number of scale marks to be drawn.
