Redmer Controls Inc. · ~2003–~2010 · LUCHT Digital · ISA
The DVP2 brought the time-saving accessories that professional photo labs had given up on — quadrant backprinting, package cutting, optical text marking, single-and-package punching — onto a fully-digital, patent-pending exposure platform. Built on a Sony 8-megapixel LCD-array print engine, a 1.5" lens-shuttle system that printed 95% of exposures without any lens movement, a GE Fanuc S2K servo paper advance, and a Microsoft Visual Basic 6.0 controller running 18 subsystems on Windows 2000 / XP. A three-company partnership: LUCHT Digital (the cabinet and lamphouse — "the world's most popular package printer"), Redmer Controls Inc. (the entire controller-software stack), and ISA / Imager Service Associates (prime contractor + distributor to the professional photo-lab industry). Productivity: 500–900 8×10 prints per hour, server dependent.
The hardware
LUCHT Digital's VP-2 was already the world's most popular package printer — its reputation for high-quality output and dependability earned across more school photo labs than any other printer on the market. The DVP2 fitted that proven cabinet, the LSB-3 lamphouse, and the existing 11×14 format with a new digital exposure engine: a Sony 8-megapixel high-definition LCD array, patent-pending optical correction, a 1.5" lens-shuttle system that eliminated lens travel on 95% of exposures, and a GE Fanuc S2K-series servo paper advance designed to keep up with the printer's new output speed. Enhanced mechanical components throughout — commercial-grade, industrial-strength, designed for 24/7 production-floor service.
The software
Redmer Controls Inc.'s DVP-2 Controller — written in Microsoft Visual Basic 6.0 for Windows 2000 / XP — drove every electrically-active component in the cabinet (the Mullersohn LCD array, the Lucht Optical Marker, the Lucht / Bremson dual back writers, the Stepping Paper Mask, the PPM and SSPM solenoid banks, the lenses, the rotary table, the pan and IRIS shutters, the paper / platen / door sensors). Eighteen named subsystems, including a Hot Folder Processor that pulled control files from every major photo-lab front-end (Kodak DP-2, Express Digital, TimeStone, Axiohm, OZE), a Shooter Data Manager for on-the-fly order editing at the printer console, a White Space Fill image renderer, and a Database Management System.
Main Screen · Manual Print Mode · Hot Folder Processor · Image Render Engine · Product Catalog · Paper Advance · Digital I/O · Serial Marker · Stepping Paper Mask · SSPM · PPM · LCD · System Timing · System Maintenance · Database Management · Error Handling · White Space Fill · Help · SDK. Each subsystem had its own maintenance window — the Paper Advance Maintenance, Marker Bar Maintenance, and Digital I/O Maintenance screens shown above are three of the eighteen.
Networked hot-folders from Kodak DP-2, Express Digital, TimeStone, Axiohm, and OZE — the lab front-ends that ran the photo industry in 2003 — dropped order files into watched folders and the DVP2 picked them up automatically. Kodak DP-2's verbatim control-file format (FILENAME / COPIES / EOO / CENTER / RESOLUTION / TONESCALE / LUTFILENAME / PAPFILENAME / MULTIPUNCH / BACKPRINTING / DELETEFILE / APPLY_LUT / APPLY_PAP / PAGE_ID) was supported one-to-one through the Control File Template Definition feature. The Folder Manager UI separated Hot Folders (administrator-defined input paths) from System Folders (Hold Queue / Print Queue / Save Queue / Database / Temp).
The Paper Advance Maintenance window provided two tabs (Paper Advance Settings + Advanced Motor Control) plus a Command History pane that captured every serial frame to and from the GE Fanuc S2K motion controller — savable to ASCII for remote troubleshooting. Each advance had its own PSA / MAC / MDC / MJK / MVL / MVA parameter row (Position Set Absolute / Motion Acceleration / Motion Deceleration / Motion Jerk Percentage / Motion Velocity / Motion Absolute distance). A bottom-status bar carried Port # + Packet Errors for live link diagnostics.
The Digital I/O Maintenance window exposed every output bit and every input sense the controller drove. Outputs: Lens Level 1–7, Lens Shuttle, Iris Shutter, Tablet Holder, Fan Shutter, Left Punch, Right Punch, SSPM Punch, PPM Punch BK1–BK6, Pin Shutter, plus reserve OPEN bits. Inputs: Lens Level senses, Iris and Pin Shutter status, Rotary Encoder, Platen Engaged, Paper Out, Paper Bar — each with per-channel ON/OFF state, Time Out interval, and Enabled flag for production-floor diagnostics.
The DVP-2 Controller embedded a subset of the standalone Shooter Data Manager (SDM) application so operators could edit Order / Frame data live at the printer console — without bouncing back to a separate workstation. Packages grid (11×14 / 8×10 / 5×7 / 3.5×5 / WALLT / SUBWL / SP-1..SP-5) over an Exposures grid (Pkg / Print / Reprint / CD / CR / CG / CB / VD / VR / VG / VB) — the fixed-format SDM file ("Shooter System / ColorFlex File Processing" in the spec — 24-byte Control Record + 22-byte Package Definition Records + 92-byte Frame Records, exactly 94,310 bytes per file).
The Serial Marker subsystem drove the Lucht Optical Marker and the Lucht / Bremson dual back writers — the printer's text-and-mark finishing chain. The Marker Bar Maintenance window let operators set when to mark (every print / on image change / on package change), tune the Optical Marker ON-Delay and OFF-Delay, set the Distance from Right Mask to Head, and define the Marker Paper Advance Length. A Command History pane on the right captured every serial frame to and from the marker hardware — savable to ASCII for remote troubleshooting — alongside a footer status bar tracking Comm Status, Packets Sent / Received, and Errors. The optical, non-RIPed text marker is what made it possible to back-print job text, customer text, and frame metadata directly onto every print on the digital workflow — without going back through a separate marking pass.
Three companies, one cabinet, the world's first digital multi-printer
The DVP2 was a three-company partnership. LUCHT Digital supplied the cabinet, the LSB-3 lamphouse, and the mechanical platform — the proven VP-2 framework already running in more school photo labs than any other printer on the market. Redmer Controls Inc. wrote the entire DVP-2 Controller software stack — 18 subsystems, every electrically-active component in the cabinet, every networked lab front-end. ISA / Imager Service Associates was the prime contractor and distributor, selling the finished DVP2 to professional photo labs alongside the existing VP-2 fleet trade-in program.

Why this case study matters
The DVP2 was, per its own brochure, "the digital multi-printer without compromise" — the first digital printer that allowed access to the time-saving accessories (quadrant backprinting, package cutting, optical text marking, single-and-package punching) that many photo labs had given up to maintain a digital workflow. That instinct to retire a legacy mechanical capability INTO a digital successor without losing what the customer base already depended on is the same engineering posture that runs through A1SI's current product line — from CVWS's legal-for-trade weighmaster workflow to TERM's 21 CFR Part 11 audit transcripts to EMDT's regulated medical-device tracking.
Per the brochure, the DVP2's electronic controls were "commercial grade, industrial-strength components designed for 24/7 use" — and the controller's Paper Advance Maintenance, Marker Bar Maintenance, Digital I/O Maintenance, and Problem Report windows were designed for line-side diagnostics on the production-floor unit. Same posture A1SI ships under today: every operator-facing maintenance surface designed to be readable on the floor, every serial-link Command History saveable to text for remote troubleshooting, every channel ON/OFF + Time Out + Enabled flag visible in one window.
The DVP-2 Controller's Hot Folder Processor consumed control files from every major photo-lab front-end of the era — Kodak DP-2, Express Digital, TimeStone, Axiohm, OZE — through a Control File Template Definition that mapped each vendor's fields one-to-one into the printer's database. That commitment to open, vendor-neutral integration informs every A1SI product line today: CVWS's open-protocol Laumas CLM8 weighing bridge, EMDT's open device-scan ingest, and the Wireless Bridges line's open-protocol RS-232 / Modbus RTU / PS-2 / Microsoft Serial Mouse coverage.
A1SI has been building production-floor controllers since 1997 — DOS/FoxPro/Watcom-C on the Ford FN-145 seat testers, Visual Basic 6.0 on the DVP2, C#/.NET on the GM ATEC EPROM programmer, and Python + Django + React Native + embedded ESP32 / NVIDIA Jetson today. Same engineering posture across every era: operator-readable maintenance surfaces, savable diagnostic transcripts, open integration with every vendor in the supply chain. If your production line needs a controller that grows with the operator workflow, we'd like to hear about it.
