Hello,

I have a HP laserjet 8150DN which works fine for the majority of our users.

When I go to print a text document under a specific user it prints in a scale of grey. All the text is present however instead of black text it is a shade of gray.

All others users work perfectly on this printer and I'm not sure what setting or adjustment can be altered to fix this problem

thanks in advance

On the computer that is printing grey go to Control Panel - Printers and Faxes if it's got XP or 2000 on it, or to Printers if it's got Win 9x/ME on it.
RIGHT click on the HP 8150DN printer icon, select Properties from the list - the setting you need to change to get it to print in black should be there somewhere.
