5.1 Bitmap Printing

There are three methods of printing bitmaps. Use the one appropriate to your purpose.

5.1.1 Explanation of Bitmap Printing

1. Normal Bit-image
The PrintBitmap method is to directly print the bitmap. One bitmap printed by this method
is formed as a combination of "n" numbers of 1-line bitmaps. So, the width of the paper sets
the limit on the size of bitmap, and printing is slow. But the height of paper doesn't set the
limit on the size of bitmap.
2. Download Bit-image
The SetBitmap method can be used to save a bitmap in the printer, and every time the
correct escape sequence (ESC |#B: Prints the pre-stored bitmap. The character '#' is replaced
by the bitmap number.) is used, the image will be printed. This method has limits on the size
of the bitmap that can be stored, but printing is very fast. If the power supply of printer is
shut off, the saved bitmap in the printer will disappear.
3. NV Bit-image
EPSON OPOS ADK provides a tool, "TMFLogo" that enables registration of a bitmap image
in the NVRAM of an EPSON TM series printer. The tool can be used from the device specific
settings of the SetupPOS utility. The bitmap image in the NVRAM can be printed with a
printer by using the DirectIO method. Concerning the available NVRAM size for the
TM-H6000II, refer to the ADG for TM-H6000II in the OPOS ADK.
