History of PCL3
PCL3 was developed by HP as a printer protocol for the early inkjet printers in 1984.
- PCL 3 was introduced in 1984 with the original HP LaserJet. This added support for bitmap fonts and increased the maximum resolution to 300 dpi. Other products with PCL 3 support were the HP DeskJet ink jet printer, HP 2932 series matrix printers and HP RuggedWriter 2235 matrix printers. PCL 3 is still in use on several impact printers which replaced the obsolete HP models.
- PCL 3+ (monochrome) and PCL 3c+ (color) are used on later HP DeskJet and HP PhotoSmart products.
- PCL 3GUI is used in most DeskJet series printers and HP DesignJet large-formate printers (plotters). It uses a proprietary compressed Raster Transfer Language format that is not compatible with standard PCL 3.
