How Do I Send a Direct Graphic to the Printer?
Once you have compressed the graphic, use the following commands to
send the RLE file to the printer.
Direct Graphics Mode, Enter
Purpose: Instructs the printer to receive RLE compressed graphics data in nibblized
format.
Default: m = 0
Syntax: <ESC>gm
where m specifies the format of the data to follow.
m = 0 8 bits per byte.
m = 1 7 bits per byte of nibblized data.
When you select m = 0, the printer parses subsequent data streams as RLE
commands. The printer still recognizes immediate IPL commands. Non-
immediate commands are not parsed. The printer resumes normal IPL
parsing when it receives an end of bitmap RLE command.
When you select m = 1, the printer receives the RLE compressed graphics
data in nibblized format. The printer converts each pair of bytes from
ASCII to their numerical equivalent and combines them to form the
original byte. For example:
ASCII Numerical Original byte
1,B 0x1,0xB 0x1B
