Draft document 2-35 Graphics USAGE NOTES • The command discards all data that goes beyond the current margin. • Text and graphics can be printed on the same line. • Each vertical dot column can have 8 rows of dots. • ESC Z high-density graphics print at half-speed of normal-density bit image graphics. • ESC Z high-density graphics cannot print horizontally adjacent dots. • See "Normal Density Bit Image Graphics (60 dpi)" on page 2-32 for more information on bit image graphics. High Resolution Graphics (259x only) For 259x printers only. This command sends data for dot matrix graphics to the printer. Format ESC [ g Ln Hn m V1 ... Vn Decimal 27 91 103 Ln Hn m V1 ...

The total number of bytes cannot exceed the number of dot columns that remain on the line. This value is represented by Ln and Hn. - When a value is represented by two parameter bytes, value (A) = Ln + Hn X 256. Calculate values of A less than 256. • Hn is 0. • Ln is the value. - To calculate values of A equal to or greater than 255. • Divide the value A by 256. • The result is Hn.

USAGE NOTES
•
The command discards all data that goes beyond the current margin.
•
Text and graphics can be printed on the same line.
•
Each vertical dot column can have 8 rows of dots.
•
ESC Z high-density graphics print at half-speed of normal-density bit image
graphics.
•
ESC Z high-density graphics cannot print horizontally adjacent dots.
•
See “Normal Density Bit Image Graphics (60 dpi)” on page 2-32 for more
information on bit image graphics.
High Resolution Graphics (259x only)
For 259x printers only.
This command sends data for dot matrix graphics to the printer.
Format ESC [ g n1 n2 m data
Decimal 27 91 103 n1 n2 m data
Hex 1B5B 67 n1 n2 m data
USAGE NOTES
•
This command allows selection of eight modes for both emulated 8-wire
graphics and 24-wire graphics.
•
Count the total number of bytes of binary bit-image data PLUS ONE (A). The
total number of bytes cannot exceed the number of dot columns that remain
on the line. This value is represented by Ln and Hn.
–
When a value is represented by two parameter bytes, value (A) = Ln + Hn
X 256. Calculate values of A less than 256.
•
Hn is 0.
•
Ln is the value.
–
To calculate values of A equal to or greater than 255.
•
Divide the value A by 256.
•
The result is Hn.
