How to Convert AFP to PS: Step-by-Step Guide for Printers
Overview
AFP (Advanced Function Presentation) is a document format used in high-volume printing environments. Converting AFP to PS (PostScript) lets you send jobs to PostScript-capable printers or workflows that expect PS.
Tools you’ll need
- An AFP-to-PS converter utility or library (commercial: IBM AFP Converter, Ghostscript with AFP plugins, or third-party converters; open-source options are limited).
- Access to the AFP files and any associated resources (fonts, overlays, images).
- A workstation or server with enough CPU and disk space for batch jobs.
- (Optional) A PDF intermediary if your toolchain prefers AFP → PDF → PS.
Preparation
- Collect resources: Place AFP files and any required overlays, fonts, and referenced images in a shared folder.
- Verify fonts: Ensure printer-accessible fonts referenced by AFP are available. If not, supply font substitution mappings.
- Test environment: Use a small sample AFP file to test settings before batch processing.
Step-by-step conversion (command-line example)
Assuming a generic converter CLI named afp2ps:
- Convert a single AFP:
Code
afp2ps input.afp -o output.ps
- Preserve or embed fonts (if supported):
Code
afp2ps input.afp -o output.ps –embed-fonts
- Convert all AFP files in a folder:
Code
for f in /path/to/afp/*.afp; do afp2ps “\(f" -o "/path/to/ps/\)(basename “$f” .afp).ps”; done
- Use PDF as intermediary (if converter converts AFP→PDF then PDF→PS via Ghostscript):
Code
afp2pdf input.afp -o output.pdf gs -sDEVICE=ps2write -o output.ps output.pdf
Batch processing & automation
- Use shell scripts or Windows PowerShell to iterate files and log results.
- Add error handling: move failed files to a separate folder and capture converter exit codes.
- Schedule with cron or Task Scheduler for regular jobs.
Quality checks
- Open resulting PS in a viewer (Ghostscript/GSView) or send to a test printer.
- Verify layout, fonts, embedded images, and page order.
- Compare job pages with original AFP to ensure fidelity.
Troubleshooting
- Missing fonts → supply font files or enable substitution.
- Broken layout → check overlays and resource paths; ensure converter supports AFP features used.
- Large files or slow conversions → increase CPU, process files in parallel, or use a dedicated conversion server.
Recommendation
For production printing, use a tested commercial converter that supports AFP features your jobs use; validate with test runs and automate with scripts for reliability.
