High-Speed Double-Density Dots; No Overlapping Dots - Epson FX Series User Manual

Pattern

Figure 11-1. High-Speed Double-Density dots
To check this out, change the pin patterns in line 30 from 85 to 127,
the sum of the labels for pins 1 through 7:
30
B$=CHR$(127)+CHR$(42)
As Figure 11-2 shows, the repeated dots, the ones called for by the
CHR$(42)-pins 2, 4, and 6-are not printed at all. The print head is
moving too fast to retract the pins and then instantly fire them again,
so the FX's program suppresses them.
