HP provides two different Universal Print Drivers: PCL 6 and emulation PostScript. PCL is a proprietary HP page description language, thus built in to their printers. Custom default values can be assigned with the HP Driver Configuration Utility. HP UPD is available in 32-bit or 64-bit, with 35 currently supported spoken languages for the ...
sRGB is a standard numerical encoding of colors, based on the RGB (red, green, blue) color space, for use on monitors, printers, and the World Wide Web.It was initially proposed by HP and Microsoft in 1996 [2] and became an official standard of the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999.

The difference between the non-photo blue and black ink is great enough that digital image manipulation can separate the two easily. If a black-and-white bitmap setting is scanned in, the exposure or threshold number can be set high enough to detect the black ink or dark images being scanned, but low enough to leave out the non-photo blue.
It must be noted that not all systems using 16-bit color depth employ the 16-bit, 32-64-32 level RGB palette. Platforms like the Sharp X68000 home computer or the Neo Geo video game console employs the 15-bit RGB palette (5 bits are used for red, green, and blue), but the last bit specifies a less significant intensity or luminance.
It was designed to encompass most of the colors achievable on CMYK color printers, but by using RGB primary colors on a device such as a computer display. The Adobe RGB (1998) color space encompasses roughly 30% of the visible colors specified by the CIELAB color space – improving upon the gamut of the sRGB color space, primarily in cyan ...
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
Sixteen bits per sample (65,536 levels) is often a convenient choice for such uses, as computers manage 16-bit words efficiently. The TIFF and PNG (among other) image file formats support 16-bit grayscale natively, although browsers and many imaging programs tend to ignore the low order 8 bits of each pixel. Internally for computation and ...
[9] [10] The original ScanJet has an internal raster image processor (RIP), controlled by software, capable of outputting the scan to the computer in raw 4-bit grayscale, in halftone dither, or in 1-bit monochrome. [9] [11] HP sold the original ScanJet with an optional automatic document feeder (ADF) attachment, intended for scanning multiple ...
