must send the set characters per line command ( GS t ) followed by the set print
orientation command ( GS V ). Because the Epic 950 does not print objects immediately
in landscape mode, multiple objects can be placed on the same line. The set horizontal
starting position (
ESC X ) and set vertical starting position ( ESC Y ) commands allow
objects to be placed at any location within a landscape page. In the case of objects
positioned to overlap each other, the first object that is sent to the printer will be printed
in the overlapping area.
Objects that would normally print below the bottom of the landscape page can be either
wrapped to the next ticket or truncated by using the select line wrap/truncate modes
command (
GS T ). Unless the set vertical starting position command ( ESC Y ) is used,
the first object sent will be printed at the top of the landscape page.
General Notes
The Epic 950 Printer may be in only one print mode at a time. Multiple areas may be
printed in different print modes on a single ticket, but these areas may only be adjacent
to one another, they may not overlap.
In any mode, the set feed length command (
GS L ) is used to determine how far the Epic
950 will feed in search of a Black Dot/Top of Form indicator. If the Epic 950 finds a Black
Dot/Top of Form indicator before the maximum feed distance is reached, it will stop at
that point, rather than continuing. This command is only needed when dealing with
continuous-feed tickets.
