Ruled Lines - Epson GQ-3500 User Manual

Ruled Lines

With the GQ-3500, you can easily draw ruled lines, which are
very useful in making forms. Although line drawing is a very powerful
feature, the command format is rather complex. Before you use the
command, you'll need to figure out:
The type of line (five different styles are available, shown on
page 6-9)
The distance from the left edge of the physical print area (the
GQ-3500 cannot print within l/4" of the left edge of the sheet) to
the starting point of the line, in 1/3OOths of an inch
The distance from the top edge of the physical print area (the
the starting point of the line, in 1/3CKIths of an inch
The direction of the line (either horizontal or vertical)
The weight, or thickness, of the line, measured in l/300& of an
inch
The length of the Line, measured in 1/3CKXhs of an inch.
With the above information, you'll need to make some
calculations. because your computer can only represent numbers up to
255 in a single character and many measurements will be more than
255/300 of an inch, you need to break up the numbers into two
characters. To do this, divide your total measurement by 256. The
remainder becomes the first number to send to the printer; the quotient
is the second number.
Here is an example: suppose you want to make a line 4-l/2 inches
long, which could be written as 1350/300". Divide 1350 by 256. The
quotient is 5; the remainder is 70. You can verify this by multiplying
Now you have everything you need to draw a line. The following
example shows how to use the ESC _ comman d to draw a line.
.
Line type: dotted (type 1)
.
Distance from left edge: l/2" = 150/300" (remainder = 150;
quotient = 0)
