Slip Station
The following illustrations show the dot patterns of sample characters for standard pitch (13.9 CPI), double-wide characters, and rotated characters (counterclockwise).
Standard Pitch
The first illustration shows a single character with the dimensions listed in the table that follows (including dimensions for compressed pitch). The second illustration shows the layout of columns for standard pitch characters.
Row spacing is fixed and column spacing depends upon the character pitch as indicated in the table.
Dimension |
Standard Pitch (13.9 CPI, 45 Columns) |
Compressed Pitch (17.1 CPI, 55 Columns) |
---|---|---|
A |
0.366 mm (0.0144 in.) |
0.30 mm (0.0117 in.) |
B |
1.45 mm (0.057 in.) |
1.24 mm (0.049 in.) |
C |
2.46 mm (0.097 in.) |
|
D |
0.353 mm (0.0139 in.) |
|
E |
1.83 mm (0.072 in.) |
1.49 mm (0.0585 in.) |
Note: Columns overlap within the format for each print row in half-dot increments (depending upon pitch), but the printer cannot print overlapping dots on a single print row. No ASCII character contains overlapping dots on a print row.
Double-Wide Characters
Double-wide characters are upright characters in an 8x7 dot format with twice the column (horizontal) spacing between printed dots as for standard characters.
Rotated Characters
Rotated characters are alternate characters in a 5x7 dot format printed 90 degrees counterclockwise (as shown in the illustration) or clockwise. Only one horizontal pitch is available: 6.95 CPI, 33 columns maximum.
