FX-286E DOT GRAPHICS
Dot graphics allows you to print individual dots at any position on the page, and thus to print pictures as well as text. While in graphics mode, emphasized, double-strike. expanded, underlined, subscript and superscript remain as set, but are inactive.
The FX-286e printer doesn't adjust the line feed increment automatically on entering graphics. If contiguous vertical graphics is desired, then set the line feed increment to 8/72 inch before starting graphics and then reset it when finished. See Line Spacing
Commands on page 134.
An FX-286e graphics control sequence starts with an escape combination that sets the graphics density (ESC K, L, Y, or Z).
followed by a 2-byte header that shows the number of subsequent bytes that are to be interpreted as graphics data. The format of the sequence is:
ESC (density) (n1) W) (data) ... (data)
Since this control sequence has no terminator, you need to specify exactly in the header the number of bytes that you want to be interpreted as graphics. If there are fewer graphics data bytes than specified in the header, then the printer treats subsequent text and control codes as graphics. In that case, carriage returns and line feeds are often ingested as graphics data.
On the other hand, if there are more graphics data bytes than specified in the header, then the printer interprets excess bytes as text or control codes. Mils can also produce very interesting results.
Specifying Graphics Line Length
The two bytes (n1, n2) specify the total number of image bytes that follow; n2 is the most significant byte.
total number of image data bytes = n1 + (n2 x 256)
Example: To print 5 inches of graphics at ESC K density, which is 60 dpi, then: total number of bytes = 5 inches x 60 dpi - 300
300/256 = 1 with a remainder of 44 n1 = 44 n2 = 1
The sequence sent to the printer (shown in BASIC) would look like:
CHR$(27);CHR$"K";CHR$(44);CHR$(1);CHR$(v1);. . . CHR$(v300); where v1 through v3OO are image data bytes.
