Graphic print direction
You can choose unidirectional or bidirectional as the print
direction for graphics. The printer usually prints text
bidirectionally for fast printing and prints graphics
unidirectionally for precise vertical alignment of print dots.
To print graphics faster, select bidirectional printing.
Software
You can select the kind of printer commands used by your
printer.
When you select ESC/P 2 , the printer emulates an EPSON
ESC/P 2 printer. When you select IBM X24E, the printer
operates as an IBM Proprinter
EPSON ESC/P 2 printer in your software programs. This will
allow you to use the most advanced font and graphics handling
available. (Emulation means that the printer can understand
and respond to commands as if it were an X24E.)
AGM (Alternate Graphics Mode)
When AGM is set to On, the printer can use high-resolution
24-pin graphics commands. The default setting is off. When
you select IBM X24E, this setting is available.
Auto line feed
When the auto line feed feature is on, each carriage return (CR)
code is accompanied by a line feed (LF) code. If your printed
text is unexpectedly double-spaced, set this feature to Off. If
text lines print on top of each other, set it to On.
