Creating a New .xpr File

When you create a new .xpr prolog file, you specify only the values that differ from the default.

The following table lists the mp program defaults for different keywords if these values are not specified in the .xpr file for the STARTCOMMON/ENDCOMMON section:

No default values are needed for the other two sections bound by STARTPAGE/ENDPAGE and STARTCOLUMN/ENDCOLUMN.

To create a page with no decoration, use four logical pages per physical page in portrait format. Specify the following sections and values:

• STARTCOMMON

• NUMCOLS 04

• LINELENGTH 20

• ENDCOMMON

When you create a page with no decoration, you do not need to specify the following two sections:

• STARTPAGE/ENDPAGE

• STARTCOLUMN/ENDCOLUMN

These parameters are not needed if you are not putting decorations on the printed page. All the coordinates are in 300 dpi by default unless you are not specifying the PROLOGDPI keyword. If the target printer resolution is different, the .xpr file is scaled to fit into that resolution by the program.

Before you create an .xpr file, you must know the paper dimensions. For U.S. paper, 8.5x11 inches, for a printer of resolution 300 dpi, 2550X3300 are the total dimensions. Most printers cannot print from the top left corner of the paper. Instead, some margin space is assigned around the physical paper. Even if you try to print from 0,0 the printing will not be in the top left corner of the page. Consider this limitation when you create a new .xpr file.
