• When disabled, the physical distance between the thermal head position and the cut position (12.12 mm) becomes the top margin of each receipt.
• When enabled, the top margin is set to 16.8 mm and the printers always holds 37 raster in the print buffer. The raster images held in the printer buffer are pushed out by the cut command.

When Compatible Top Margin is enabled, the user also needs to set the value (0.1 to 25.5 seconds) for the Compatible Top Margin Timeout.

This parameter sets the number of seconds before the printer pushes out the data held for Compatible Top Margin. Instead of waiting for the cut command to print the held data, the printer prints the held data after the set timeout value has lapsed.

This parameter provides the following options:

• CP437/858 Large — the character size of CP437 and CP858 are large, though the font cell is same as original font. In other code pages, it is the same as the original font.
• 866 Mini — the size of CP866 Font B is 10(W) x 14(H) dots.
• Constructed 874 (refer to Thai Code Page Function)
• Contextual 1256 Proportional Pitch (refer to Arabic Font Support)
• Contextual 1256 Fixed Pitch (refer to Arabic Font Support)
• Greek — CP850 (DOS Latin 1) maps to CP928 (Greek), and CP874 (ISO Thai) maps to CP737 (DOS Greek)
• SBCS2 (refer to SBCS2, SBCS3 Font Support)
• SBCS3 (refer to SBCS2, SBCS3 Font Support)
