I have been using various color HP printers for graphical output in a device.
The device is PC based. I wrote a simple driver using HP PCL to do a screen capture. It sets the number of raster planes per row to 4 planes KCMY palette (Esc * r -4 U). This driver has been working (unrevised) and without problems for 10 years. When I use the Inkjet 1200, it puts the Black, Cyan and Magenta planes down but not the Yellow. Self Test shows yellow working. Any help? Thanks
