My HP Photosmart 8150 has started printing color

That is entirely up to your personal preferences. I sue black foa almost all except things like coupons and other documents that the color is needed to make it useable.

Here is the manual for the printer: http://h10032.www1.hp.com/ctg/Manual/c00230474.pdf , but there is not a reference for mirror image printing. Check your application software for capability to mirror print.

There are advanced options in your browser to specify Use My Colors versus Default.
Also uncheck Print Background images

Open a document or type something into wordpad,then go up to file,then print.Select the 8150 and go to properties.Somewhere in there,you'll see an option to print B&W or color.Make sure it isn't set to B&W.Should work with your other printer too.

Scan an image
You can start a scan from your computer or from the HP All-in-One. This section
explains how to scan from the control panel of the HP All-in-One only.
To use the scan features, the HP All-in-One and computer must be connected and
turned on. The HP Photosmart Software (Windows) or HP Photosmart Mac Software
(Mac) must also be installed and running on your computer prior to scanning.
● On a Windows computer, look for the HP Digital Imaging Monitor icon in the
Windows system tray (at the lower right side of the screen, near the time) to verify
the software is running.
Note Closing the HP Digital Imaging Monitor icon in the Windows
system tray can cause the HP All-in-One to lose some of its scan
functionality. If this happens, you can restore full functionality by restarting
your computer or by starting the HP Photosmart Software.
● On a Mac, the software is always running.
Tip You can use the HP Photosmart Software (Windows) or HP Photosmart
Mac Software (Mac) to scan images, including panorama images. Using this
software, you can also edit, print, and even share your scanned images. For
more information, see the onscreen Help that came with the HP All-in-One.
To scan to a computer
1. Load your original print side down in the right front corner of the glass.
2. Press Start Scan.
3. Press OK to select the default application to receive the scan, or press to
select a different application, and then press OK.
A preview image of the scan appears on your computer, where you can edit it.
4. Make any edits to the preview image, and then click Accept when you are
finished.

One or more colors are not printing, or are inaccurate.

Sealing tape might be on the print cartridges. Verify that the sealing tape has been completely removed from the print cartridges. The media might not meet HP specifications. Use a different paper, such as high-quality paper that is intended for color laser printers. The device might be operating in excessively humid conditions. Verify that the device environment is within humidity specifications. One or more print cartridges might be low. If you are using non-HP print cartridges, no messages appear on the device control panel or in the HP Toolbox. Replace any low print cartridges. The control panel is set for override. Replace low or empty print cartridges. A color is printing inconsistently after you load a new print cartridge.

Another print cartridge might be low. If you are using a non-HP print cartridge, it might be low or empty but you will receive no indication.

The colors on the printed page do not match the colors as they appear on the screen.

The colors on your computer monitor might differ from the device output. Select Screen Match in the Color tab of the printer driver.
