Description
Pn is a number of units, depending on Positioning Unit Mode (PUM)
and Select Size Unit (SSU).
Each Pn parameter is a selected vertical tab stop. A maximum of 16
tab stops can be selected in one command. The printer can receive Pn
parameters in any order; it sorts them and places them into the tab
table.
The printer sets tab stops relative to the page origin and not to the
top margin. Changing the top margin does not charge the position of
tab stops. Changing the pitch with Set Vertical Pitch (DECVERP)
modifies tab positions to keep the number of lines between tab stops
constant.
The printer allows at least one tab per line along the longest paper
supported at the smallest built-in line spacing.
Tab stops can be set outside the current margins; however, the
printer does not use tab stops beyond the bottom margin.
Error Handling
If the printer receives more than 16 tab stops, it sets the first 16 and
ignores the rest. If the same tab stop is sent more than once, the
printer sets the tab stop once. The printer ignores a command sent
without tab stop parameters.
When the number of new tab settings exceeds the maximum, the
printer discards the tab stops with the highest values.
