My printer works great but the print density is set at "3" so the printing is very light. I can only connect it by USB. H-P doesn't seem to have any drivers that will work with my new iMac and this old but great printer. Can the print density be reset on the printer itself? Economode has been deselected. I do have an older iMac running Mountain Lion and I am considering trying it on that but I don't think Mountain Lion will connect to H-P. Thanks in advance!!
Are the built-in reports and demo pages light as well? If so this is likely a toner cartridge issue and not a hardware failure or driver issue.
