clearance will vary. This clearance can be observed from the
offset pattern printed in bottom of self test.
Whenever the lower part of the long vertical lines is shifted
horizontally away from the upper part by about one dot width, the
offset value should be adjusted to move it back for decent print if
bi-directional print is engaged. Increasing the offset value by
changing the S1 setting can move the lower part to right and
decreasing the value moves the lower part to left.

Positions 1 to 6 of the S2 switch define the communication
protocol and handshaking criteria in RS232 interface. They will
present no influence if parallel interface is used.
Position 7 of S2 alters the horizontal spacing between
characters to get different print density on same font format.
Position 8 of S2 determines whether to print only in one
direction of print head operation or in both directions.
All positions of S2 default to OFF when printer delivered.
