Architecture & Stack

Built for Precision

PrintCatalog combines a modern web frontend with a high-performance Rust backend to provide professional-grade printing precision.

The Precision Problem

Achieving sub-millimeter precision in photo layouts is challenging with standard document printing tools. High-resolution photos are often downscaled, and layout margins can shift—ruining passport grids.

PrintCatalog uses a custom native printing pipeline for absolute control.

The GDI Solution

We use the Win32 GDI (Graphics Device Interface) through the Rust windows crate. This allows us to send raw pixel data directly to the printer's device context.

By using StretchDIBits with HALFTONE interpolation, we ensure the sharpest possible output directly from the original file data.
