8000 Page Mode
The Ithaca
®
8000 supports two operational modes, standard and page mode. In
standard mode, as a line of text is received it is buffered and printed when the line feed
is recei
ved. In page mode the printer waits for a complete ―Page‖ (a number of lines) to
be received before printing the complete page. The advantage of page mode is that text
and/or graphics can be placed anywhere on the page, in any order, and in any of 4
orientations.
How to use page mode
Page mode requires two phases to operate correctly.
1) Page definition (placing data on the page)
2) Printing the page.
Page Definition
The [ESC]t command will start page definition and define the initial orientation. An
[ESC]t command during page definition will change the orientation and reset the entry
location back to the top left corner of that orientation.

Auto-cutter and page mode
You may embed an auto-cutter command with in a page definition, provided the page
will be printed on the receipt station. The auto-cut command may be placed anywhere in
the page definition, however, it will be processed after the page is printed. To prevent
the cut from occurring in the page, it will be preceded with a feed that will place the end
of the page about 0.125 inches above the auto-cut position.
Mechanism commands in page mode
In general, mechanism commands received during page mode will be processed if the
result will not effect the printed result. For example, the bell and cash drawer commands
will be processed as they are received.
