7.1.1 Data Page
What is a data page and what is the data page buffer?
A data page is the amount of data that can be printed on a page.
Data is typically formatted in order to print correctly on the media for which it is destined, and a data page
corresponds to the amount of data that can be printed on a page of a specific size and configuration. For a
piece of plain paper, it may be a given number characters per line and lines per page, and for a pay slip or
any preprinted form, it may be a number of data fields per form.
When you create a document with PlanetPress Design, you can give it the size and structure you want, so long
as the configuration you create is compatible with your printing devices.

Data Page Buffer
The data page buffer is a two-dimensional array that the document uses at runtime to store one or more data
pages. Imagine a table with a specific number of rows and columns, where each cell contains one character of
input data.
7.1.2 Hex Viewer
What is the Hex Viewer and why might I use it?
The Hex Viewer is a tool for viewing the characters in the sample data file as hexadecimal values. ASCII
characters appear on the right side of the Hex Viewer, and the corresponding hexadecimal values on the left
side. This is useful when you are selecting an emulation or fine-tuning the size and structure of the data page.
