Epson GQ-3500 User Manual page 110

0: Delete image from printer memory
1: Define graphic image (data follows this command)
2: Print defined image
3: Define image (same as 1) and print image at current print
position
The value of n2 (from 1 - 8) specifies the number assigned to the image.
The value of n3 and n4 specifies the horizontal distance from the
logical origin (Y-axis) to the left side of the image in units of the
minimum increment. The value of n5 and n6 specifies the vertical
distance from the logical origin (X-axis) to the top of the image. In
each case, the distance is determined using the formula: nl + (n2 x 256).
Values should be specified for n3, n4, n5, and n6 only when nl is 2.
Note
The graphic primitive commands that follow should be entered as
ASCII strings followed by a carriage return (indicated as <CR> in the
format). The parentheses and commas shown are required. When you
are done defining your graphics, you must finish with the EXIT
command and a carriage return. See Chapter 6 for sample graphics
programs.
ALLOCATE
Format:
ASCII code:
Comments:
This command reserves an area for preparing graphic images with the
simplified graphics functions. The width, in units of the minimum
increment, is defined by nl. The height is defined by n2. Both
parameters should be entered as decimal integers, with a comma
separating the two.
CIRCLE
Format:
ASCII code:
Comments:
Draws a circle or an arc in the graphic area reserved by the ALLOCATE
command. The value of nl and n2 specifies the X- and Y-coordinates,
respectively, of the center of the circle. The value of n3 specifies the
radius of the circle. These are the only required parameters.
