rastertofax
rastertofax is a utility from HP that converts raster image data (typically PostScript or PDF) into TIFF-based fax format suitable for transmission via fax modems or fax services. It is typically invoked by printer drivers or fax-related workflows rather than launched directly by users. The app is part of HP's print and fax infrastructure on macOS and serves professionals and organisations that still rely on fax transmission as part of their document workflows.
AI Recommendation
1 suggestionWe found no public information about whether HP has shipped a native Apple Silicon build of rastertofax. Because this is a utility component rather than a user-facing application — it runs silently as part of a broader print or fax workflow — it is often updated as part of HP's printer driver package rather than as a standalone product. Check your HP printer driver version by opening System Settings → Printers & Scanners, selecting your HP printer, and clicking "Supply Levels" or "Options & Supplies" to see if driver updates are available. HP's driver support pages and AutoUpdate utility should detect and install any native Apple Silicon builds automatically. If you use fax features regularly and are concerned about compatibility after macOS 28 ships in September 2028, contact HP support directly with your printer model to confirm they have shipped Apple Silicon drivers for your device — they are generally more responsive to direct requests than public documentation is.
