27 68 list 0 This sequence clears all current horizontal tab stops and
sets new tab stops using the current character spacing. Tab stops
can be set at any of the first 159 print positions on a line. Epson
and IBM horizontal tabs are absolute, which means that the
physical location of the tab stops on the page are unaffected by
changes in character spacing. The list in the sequence is a series
of bytes that define where to set the tab stops, and must be listed
in ascending order. The last byte of the sequence must be a
NUL or a code less than the last tab stop defined in the list. For
example, to set abso-lute horizontal tab stops every inch at 10 cpi,
the correct sequence is 27 68 10 20 30 40 50 60 70 80 90 100 110
120 130 0 (decimal). To clear horizontal tab stops without set-
ting new ones, omit the list from the sequence. To set hori-zontal
tab stops with proportional-spacing selected, use 12 cpi when
specifying the tab stop locations.
If the factory defaults are in effect, horizontal tab stops are set
every eight print positions across the page. To reset horizontal
tabs every eight print positions across the page, use the Set
Absolute Horizontal Tab Stops Every Eight Print Positions
sequence.
Note: This sequence is not supported when the IBM XL24
emulation is active.
27 66 list 0 This sequence clears all current vertical tab stops and sets
new tab stops using the current line spacing. Epson and
IBM vertical tabs are absolute, which means that the physical
location of the tab stops on the page are unaffected by changes in
line spacing. The list in the sequence is a series of bytes that
define where to set the tab stops, and must be listed in ascending
order. The last byte of the sequence must be a NUL or a code
less than the last tab in the list. For example, to set absolute
vertical tab stops every inch at 6 lpi, the correct sequence is 27
66 6 12 18 24 30 36 42 48 54 60 0 (decimal). To clear vertical
tab stops without setting new ones, omit the list from the
sequence.
27 82 This sequence clears all current horizontal and vertical tab
stops and sets new horizontal tab stops at every eight print
positions using the current character spacing.
Note: This sequence is not supported when an Epson
emulation is active.
