Graphic Mode
The Epic 880TM Printer conforms to the basic definition of IBM all-points-addressable
(APA) graphic commands. It is not designed to print large quantities of graphical data.
The printer only prints graphics that are 2.5 inches wide. At this time, there is no
graphics mode for Epson emulation.
The Epic 880TM Printer always prints in one of the native resolutions of 203 x 203 dpi.
To provide compatibility with the standard IBM APA resolutions, the printer internally
modifies the graphics to print as expected. The printer converts the vertical resolution
by altering the [ESC] J command (which is typically used for vertical spacing) and
adjusting it so that horizontal passes touch as expected. The requested horizontal
resolution is converted by data scaling. Because the vertical dpi of the printer is
always greater, the resulting APA graphics printed on the Epic 880TM Printer may be
slightly smaller or larger than the same graphic printed on an impact printer. All of this
is done transparently to the application; however, loss of resolution may result in
some modes. If desired the [ESC] * <m> command can be used to select the native
resolution.
Note 1: If the Epic 880TM Printer is used with programs that convert text to
graphics, the printer is slower than if the printer is sent ASCII text. The Epic
880TM Printer is supported by a Windows’ print driver that allows applications
to select internal supported fonts.
Note 2: Generally, the horizontal graphic commands provide faster print
than the APA graphic commands.
Standard APA Graphics
[ESC] K Print single-density graphics (60h x 72v dpi)
ASCII [ESC] K <n1> <n2>
Hexadecimal 1BH 4BH <n1> <n2>
Decimal <27> <75> <n1> <n2>
IPCL none
Description The [ESC] K <n1> <n2> command prints <n1> + 256 * <n2> bytes of
single-density graphics (60 dpi).
[ESC] L Print half-speed double-density graphics (120h x 72v dpi)
ASCII [ESC] L <n1> <n2>
Hexadecimal 1BH 4CH <n1> <n2>
Decimal <27> <76> <n1> <n2>
IPCL none
Description The [ESC] L <n1> <n2> command prints <n1> + 256 * <n2> bytes of
double-density graphics (120 dpi) at half speed, allowing full and half dots to be
printed.
