Scanning is done in single scanlines (one pixels height). The scanning procedure waits while FBEFh.Bit2=0 (which probably indicates that the head is in the left-most position, or that it has just leaved it, or so). The horizontal "dot clock" is implemented as software delays. When scanning a black dot, one or more bits in Port FBEFh become non-zero (not sure which bit; the driver software simply checks "IF Port[FBEFh]<>FFh THEN PLOT pixel").
Observe that the manual includes some patches for usaging the scanning software with different printers.

Observe that the manual includes some patches for usaging the scanning software with different printers, ie. it may be required to do some small modifications before using the above drivers.
