Deskjet Plus 4100 printer won't print black

[barobinson]

When I lay a sheet to be printed on the printer glass and push the black button, it won't print black. I've tried also pushing the color button but still no black print.  When I try feeding it thru the top feeder, I get the same results; no black print.   It will print color but not black.  It prints both black and color when I make a print request from my laptop.  I've tried disconnecting and resetting but it's still doing the same thing.  

Suggestions?

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Are you able to make a black copy from the printer?
• Have you tried changing the print settings before printing in black?
• What's the application you are trying to print from? 
• Have you tried printing from a different application or device? 

While you respond to that, let's try these steps: 
Print a Print Quality Diagnostic page in Windows using HP Printer Assistant.

Load paper into the input tray.

Open or search for the HP folder in your list of installed software programs, click the folder for your printer, and then click the name of your printer.

The HP Printer Assistant software opens.

On the HP Printer Assistant window, click Maintain Your Printer.

Click the Device Services tab, and then click Print Quality Diagnostics Page ().

The printer prints the Print Quality Diagnostic Page.

Examine the colour blocks on the Print Quality Diagnostic page to make sure that the colour blocks do not show white lines, and are not faded or missing.

Hope this helps! Keep me posted for further assistance.
