The MicroPrint 45CV/CH interface converter allows parallel printers with Centronics parallel interfaces to be used with the IEEE-488 (HP-IB/GPIB) bus. The device supports the IEEE-488 subsets: SHO, AHI, TO, TEO, L1, LEO, SRO, RLO, PPO, DCO, DTO, and CO.

This MicroPrint 45CV/CH is equipped with the Variable Resolution and HP-GL (HP Graphics Language) features. Variable resolution allows you to adjust the size of raster(bit mapped) graphics output in portrait orientation when using HP dot matrix, DeskJet, & LaserJet printers. Variable resolution allows adjustment of the raster graphics size in landscape orientation when using HP LaserJets only. See the Variable Resolution section below for more information. The HP-GL mode allows HP LaserJets which use PCL 5 (Printer Control Language, version 5 or later) to be used as plotters. See the HP-GL section below for more information.

The MicroPrint 45CV/CH is an interface converter, not a printer emulator. Your software must send the correct data format to the MicroPrint and printer. HP computers and test instruments send text and raster graphics data to printers in PCL format, and vector graphics data in HP-GL format. All HP printers accept PCL data and all HP plotters accept HP-GL data. Unless you are printing text only, you must use an HP-compatible printer with the above HP (or comparable) equipment. Consult your computer or software manual to ensure the printer you wish to use is supported before connecting the MicroPrint.

The input connector is a 24 pin IEEE-488 female "D" connector with metric screw lock hardware. The output connector is a female 25 pin "DB25" type connector with screw lock hardware. The pinout of the parallel port is compatible with the IBM PC-type parallel printer interface cable. The MicroPrint 45CV/CH is powered by a 9V AC or DC wall-mounted power adapter.
