FUNCTION 3: Text scale mode
This setting determines how many lines fit onto a page by adjusting the
line spacing. If you are using a software application that assumes 66 lines
will fit on each page, set this FUNCTION to ON. The printer will reduce
the line spacing by a factor of 62/66, which is from 62 lines per page to 66
lines per page if line spacing is set to 6 lines per inch (lpi).
FUNCTION 4, 5: Top margin
Use these functions to set the size of the top margin. Once selected, this
setting takes effect when the next sheet of paper is fed.
The default setting is 0.12 inch (3 mm) because the default printer control
mode is BJ mode. When you change the control mode to Epson LQ mode,
the top margin will be changed to 0.33 inch (8.5 mm).
FUNCTION 6: Smoothing mode
Set this FUNCTION to ON to enable the Smoothing mode, which is used
with the BC-10 Black BJ cartridge only. When Smoothing is enabled, the
printer refines your printout by polishing away the jagged edges and
ragged stair-stepping curves of characters and graphics. This results in
sharp and crisp printout at 720 (horizontal) by 360 (vertical) dots per inch.
N
When to set FUNCTION 6 to ON
Enable Smoothing mode when printing from MS-DOS applications with
the BC-10 Black BJ cartridge using the printer's internal fonts. Smoothing is
especially effective for printing double height, double width, italic
characters, and combinations of these characters.
FUNCTION 7: Automatic power off mode
The printer is idle when it receives no data and no instructions from the
operator panel. This FUNCTION setting allows you to configure your
printer to turn itself off automatically if it is continuously idle for 30
minutes. This function is a convenient way to maximize battery life. The
factory default is Disabled.
FUNCTION 8: Font typeface lock mode
This function is called the Font typeface lock feature. It determines whether
the font selected from the operator panel may be overridden by a DOS
software application. The factory default is Disabled.
When you set this FUNCTION to OFF, the fonts specified by your software
applications are used at print time. Set this FUNCTION to ON when you
want the fonts specified through the operator panel to take precedence over
the font selections made by your software application.
FUNCTION 9: Input/download buffer
This function controls the size of the input and download buffers. The
amount of memory reserved for the data input and download buffers is
35 KB in BJ mode and 26 KB in Epson LQ mode. This function specifies
whether to use this memory exclusively as an input buffer, or to split it
between an input buffer and a download buffer. The factory default setting
specifies that the memory is used exclusively as an input buffer.
