The values to use for each of the parameters are covered in
Appendix A. Like the ruled line command, all measurements are given
in
1/3OOths
of an inch. The GQ-3500 printer prints using dots that are
1/3OOths
of an inch wide, thus the measurement
value
equals the
number of dots needed to print an image. Because parameters are
entered as ASCII strings in the graphics mode, no mathematical
conversions arc necessary.
Printing images
As the previous sample programs demonstrate, the ESC
I
1
command is used to print images as well as store them. For printing,
however, it is followed by a few more parameters.
Before you can print an image, you must determine where you want
the image to print on the page. Like the ruled line command, the
measurements should be made in
1/300ths
of an inch, starting from the
edge of the physical printing area, which is
l/4”
from the left edge of
