l Pages in buffer: Enter the number of data pages you want the data page buffer to contain, or use the spin buttons to
increment or decrement the value. Putting more pages in the buffer multiples the lines shown and is only useful in spe-
cific cases. You should also consider using the "N-Up Object" (page 147) if you want to display multiple data pages.
l Cut on FF character: Select to have the document start a new data page when it encounters a form feed character
in the data stream. If you select Cut on FF character, you have two conditions that signal the end of a data page: the
form feed character and the number of lines set in the Lines per page box. Note that the Cut on FFcharacter takes
precedence on the lines per page option.
l Read in binary mode: Select this option to force the printer to read the incoming data in binary mode. Use this
option with the ASCII emulation to fix problems related to line spacing caused by LFCR character pairs found within the
data. Use it with the ASCII emulation and with the Tab on carriage return option to fix problems related to data for-
matting caused by isolated CR characters found within the data. This option can only be used with the ASCII and User
defined emulations. Note that you cannot select this option if the document is to be installed on a printer that cannot run
in binary mode.
l Data encoding: Select the appropriate encoding for the sample data file. You may look at the data in the Data pane
(non-English characters especially, if any) to see how the your selection affects the data.
Line Printer Emulation
Line printer emulation tells the document to treat the input data as data destined for a line printer.
In this emulation, a form feed signals the end of a data page. If no form feed occurs in the data stream, the emulation adds
lines to the data page buffer until the buffer is full.
Line printer emulation offers the best overall performance of all the emulations.
Line Printer Emulation options
The line printer emulation does not have any options other than the general text-based emulation options (see "Text-Based
Emulation Properties" (page 90))
ASCII Emulation
ASCII emulation tells the document to treat the input data as a stream of ASCII characters. The document reads the data
stream one character at a time, constructs a line, and adds that line to the data page buffer.
In this emulation, you can define how the document handles carriage returns that are not followed by line feeds and how it han-
dles tabs. You can also define whether you want the document to remove any Hewlett Packard Printer Control Language (HP
PCL) escape sequences it encounters.
If you use an ASCII emulation, you need to know if your printer supports binary mode as this is the recommended mode for
ASCII emulation. On printers that support binary mode, you can switch the printer to binary mode using the printer keypad or
by sending the appropriate PostScript code to the printer.
In binary mode, the printer reads the end of line characters (carriage return [CR], line feed [LF], and carriage return followed
by a line feed [CRLF]) as they appear in the data stream and does not perform any substitution. A printer that does not support
binary mode or is not running in binary mode replaces any CR, LF, or CRLF that appears at the end of a line of data with a LF.
A form feed signals the end of a data page in ASCII emulation. If no form feed occurs in the data stream, the emulation adds
data to the data page buffer until the buffer is full.
ASCII emulation options
l Tab on carriage return:Select this option to fix formatting problems caused by isolated CR characters found within
the data. When this option is selected, isolated CR characters are spaces, as defined in the Number of spaces in
