7520e: black and white prints have blue cast

Question

Black & white prints have a blue tinge to them and are not true black and white.
Is there a good explanation of what all the various controls do, in the Print dialogue boxes?
Thanks.

Hi @organgrinder,
Your print Dialog box sometimes varies depending on which program you are printing from, but, I found some potentially helpful information about advanced color management;
Using the default sRGB modeThe default sRGB color space is the most common setting for print jobs. As mentioned, most images are sRGB, and using sRGB delivers automatic high-quality color without user intervention. When sRGB is selected, the driver controls the color management. Color management should not be attempted with ICC profiles while the driver is set to sRGB mode. Doing so will usually result in lower color fidelity.
Using the AdobeRGB mode
The AdobeRGB Color Space mode is designed to provide compatibility with emerging camera functionality. This mode can be used for printing photos from digital cameras that support the Adobe RGB color space. For example, if a camera is set to Adobe RGB while capturing photos, those photos can be printed from any application by using this color space selection. For print jobs that involve significant editing or graphics composition in the Adobe RGB color space, ICC color management may give better results. Color management should not be attempted with ICC profiles while the driver is set to AdobeRGB mode. Doing so will usually result in lower color fidelity.
Using the ICM color management mode
ICM color management should be selected for the following reasons:Creating ICC profiles to manage printer color
When using an application such as Adobe Photoshop, which supports the selection and use of ICC profiles.
From the perspective of the printer driver, the ICM Color Management selection does one simple thing: it turns off printer color management. If this option is selected from an application that does not allow for the use of ICC profiles, or if no profile is selected for the printer, the resulting prints will be dark, vivid, unmatched printer colors. By disabling printer color management, the high-end user has complete, control over the color matching process via the application.
