WordPerfect Printer Data

WordPerfect printer data (also known as Corel WordPerfect general printer information) is a binary resource file created by WordPerfect during printer driver setup in DOS and early Windows (WP 5.x / 6.x era). It contains shared configurations for groups of printers - defining how WordPerfect should talk to those printers. Typical contents include paper size definitions, font metrics, hardware configuration tables, and printing capability flags. The program then uses this file when you install or edit a printer driver to extract a more specific printer resource (.PRS) file matching your exact printer model.

These files were introduced in the late 1980s and became obsolete after Windows-95 and later versions of WordPerfect adopted native Windows printer drivers. Modern WordPerfect Office versions no longer use printer resource data from these files; they persist only in legacy environments.

The file format usually begins with a signature of four bytes 0xFF 57 50 43 ("ÿWPC") at offset 0, followed by a byte at offset 8 indicating subtype 0x13 identifying this as printer resource data (WordPerfect printer data), and further header data including pointer tables. The file also includes human-readable strings such as "THIS PRINTER", "DEFINITION", "10CPI (", "ITALIC", "BOLD", "FONTS", "GRAPH", "PAGE", among others, which help WordPerfect locate specific printer features.
