The Intelligent Interfaces MicroPrint 45CH is an HP-IB to Centronics parallel interface converter that bridges legacy IEEE-488 instruments to modern parallel printers and plotters. It enables transparent data transfer at rates exceeding 40 KBytes/sec without requiring host system modifications. The converter supports variable resolution graphics (75, 100, 150, 300 dpi, with specialized support for 96/192 dpi ThinkJet/QuietJet and 90/180 dpi PaintJet), HP-GL vector plotting mode, and ATE color printing. Switch-selectable HP-IB addressing and listen-only configuration provide flexible integration into existing test systems.
