Notes about the FF1 file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The FF1 file type is primarily associated with 'PCLTool' by Page Technology Marketing, Inc.. PCLTool can parse, index, split, streamedit, view and convert HP PCL into various raster and vector formats or print to any Windows printer. PCLTool can also extract the ASCII text from PCL.
