PROPRINTER DOT GRAPHICS

Dot graphics allows you to print individual dots at any position on the page. The Proprinter doesn't adjust the line feed increment automatically on entering graphics. If you want contiguous vertical graphics, then you must set the line feed increment to 8/72 inch before starting graphics and then reset it when you are finished.

An IBM 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> <n2> (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. This can also produce indeterminate results.

The two bytes (n1, n2) specify the total number of image bytes that follow; n2 is the most significant byte.

The total number of image data bytes - n1 + (n2 * 256)

EXAMPLE: to print 5 inches of graphics at ESC K density, which is

60 dpi, then:

Total bytes = 5 inches x 60 dpi = 300

n1 = total bytes modulo 256, in other words,

n1 = total bytes – (n2 * 256)

n1 = 300 - (1 * 256)

n1 = 44

n2 = integer (total bytes/256)

n2 = integer (300/256) = 1

The sequence sent to the printer (shown in BASIC) would look like: CHR$(27);CHR$"K';CHR$(44);CHR$(1);CHR$(v1);... CHR$(v3OO); where v1 through v3OO are image data bytes.

Each image data byte represents a vertical column of eight dots. The most significant bit of the byte controls the top dot of a column, and the least significant bit controls the bottom dot of that column. The first byte of data (v1) is the first column, (v2) is the second column, and so on. The illustration below shows byte values of various dot combinations.
