HP LaserJet Pro color MFP M570 – Color printing.
The HP LaserJet M209dwe and the Brother HL-L2370DW are two monochrome laser printers with no scanners.
Monitors display colors by light pixels using an RGB (red, green, blue) color process, but printers print colors using a CMYK (cyan, magenta, yellow, and black) process.
Individual HP ink cartridges
Printers that use individual HP ink usually need a set of four color cartridges: black, cyan, magenta, and yellow.
Use the HP Smart app to check ink or toner levels from your Android or Apple iOS device. Go to 123.hp.com to install the HP Smart app on your mobile device. Add your printer to view ink or toner levels on the home screen.
Compared with inkjets, laser printers can pump out pages, both in color and simple black and white.
If the problem is isolated to one color, set the printer to Disable Cartridge Check and swap cartridges. If the problem disappears, the old cartridge was obviously bad. If the problem persists, something associated with the cartridge is to blame: its high voltage contact, high voltage circuit, or laser scanner.
First, check your printer settings on the file or picture your trying to print. If your page is setup to print in “grayscale” it will only print in black and white. Change the setting to “default” so it will print in color. If your settings look good from the start, the cartridge may just need to be primed.
Why is RGB not ideal for Printing & Packaging? In most printing processes, RGB color space is usually converted to CMYK before creating the artwork. Essentially, any colors produced with RGB on the digital space will not create the same output on the physical print.
Navigate to Window > Color > Color to bring up the Color panel if it is not already open. You will see colors measured in individual percentages of CMYK or RGB, depending on your document`s color mode.
PDF files are not RGB or CMYK – every page object can have whatever color space it wants, so the text may be CMYK, the images RGB, and the background a spot color. That`s why there`s no single statement of “color mode” anywhere on the document properties.
About RGB-CMYK
Scanners, digital cameras and computer monitors use red, green and blue (RGB) light to display color. Commercial printing presses print with cyan, magenta, yellow and black (CMYK) ink, called process printing, instead of RGB light, and therefore produce a different range of color.
Open Printer Properties and verify that the print driver indicates color support in the driver on the General tab. If the Color: setting in the Features section on the General tab is set to No, the driver is not configured to print in color.
