Jet.Engine GUI is the software that runs every Accufast Automecha inkjet printing system — the Accufast P4, P8, PM6, PM8, PMX, CKx and 22VT. Accufast closed around 2018 and manufacturer support ended by 2021, so All For Mailers hosts the complete last-known software archive right here: GUI installers, the Accufast Print Connect driver, the USB adapter driver, imager firmware, and documentation. Free, no signup — the same files our own technicians use.

⬇ Jet.Engine GUI Help File (PDF, 7.8 MB)Moving the software to a new computer
Transferring Jet.Engine GUI to a new PC or a new owner is usually not straightforward and frequently fails on modern hardware:
- No parallel port (LPT) — the software was designed for Windows XP/7 with real parallel ports; USB-to-LPT adapters often fail due to driver issues.
- Missing configuration files — installers alone aren’t enough. Calibration, timing and head-alignment settings live in INI files, the registry, or local configs on the original PC (sample of the configuration information required for a P4).
- Windows compatibility — unsupported on Windows 10/11; anything newer than Windows 7 (32-bit preferred) commonly crashes or won’t communicate.
Best recommendation: sell or transfer the printer together with its original working computer — the most reliable way to keep it running.
Licensing: no active licensing exists — no online activation, dongles or keys in known versions. Transferring files needs no authorization from a defunct company.
Keep your Accufast running — or step up
Parts position: aftermarket rollers and some bearings remain available across the Accufast line, plus motors for the KT, KT2 and XL — everything else is gone. If a board fails it may not be replaceable at any price, so put your machine on a quality surge protector with static protection. Machine acting up?
