Epson 8900 Series - Manual (Page 56)

Character Sets and Global Commands 3-25
Selecting a Font
Escape Sequence: ESC DLE f n
Hexadecimal: 1B 10 66 n
This command allows you to access type styles not specifically
supported by an emulation.
This command selects the font designated by the variable n, where n
can range from 0 through 254 decimal as follows:
Font ID No.
Courier 0
Prestige Elite 1
OCR A 3
OCR B 4
Gothic 5
Presentor 6
PostNet 7
Note: Using any value other than the valid font ID number for n,
causes the printer to accept and ignore the command, and cause a
FONT NOT AVAILABLE ERROR.
Selecting a Font’s HMI
Escape sequence: ESC DLE H
Hexadecimal: 1B 10 48
This command enables you to access natural pitches of a font that may
not be specifically supported by an emulation. The command sets
horizontal motion index (HMI) to the currently selected font’s HMI.
The command cancels the double-width print mode, but does not
cancel the oversize-character (scalable characters) command. This
command resets the Epson variable spacing to zero.
