The left margin, once set, remains effective until it is either changed by another left margin set com-
mand, or is reset to the leftmost print position by the INPUT PRIME signal from the host computer.
When the printer is powered on, the left margin is set to the leftmost print position.

13-8. Horizontal Tab Set/Clear
Up to thirty-two horizontal tabs can be set at one time. The horizontal tab command, HT (09 deci-
mal), causes the print position to move to the next tab set. The printer will ignore a horizontal tab
command if no tabs have been set, or if the print position is at or beyond the last tab set (logic seek
print mode). Tabs can be cleared selectively or entirely. The tabs are set in accordance with the cur-
rent character pitch (One character width is 16 Dot in variable length font.).
If
character pitch is
changed after setting tabs, they will no longer conform column-width - they will remain in the same
physical positions as when they were set. Therefore, tabs should be set only after pitch is selected. No
tabs are set printer is powered on.
