Hi I am using hp inktank 310. I am facing a problem that at 600 DPI black and white prints are blurred and unreadable but at 1200 DPI prints are fine. Colour prints are fine on both 600 and 1200 DPI. Kindly help me with this issue ASAP.

@UsmanHaseeb I suggest you upgrade the printer firmware using the steps mentioned here,

once done, please use the below steps to reinstall the printer drivers:

• Press "Windows key" + "r" to get the "Run" window.
• Type "services.msc" to get Services - Go to "Print spooler" - Right-click and "Stop" the service.
• Now again open "Run" - Type "spool" and ok - Go to PRINTERS folder - delete everything in that folder.
• Go to services again - Start the print spooler.
• Now check for issue resolution.
• If the issue persists, unplug the USB cable from the printer (if present). 
• Go to Control panel - Programs and feature - Select all the HP printer entries and uninstall them.
• Now go to Control panel - Devices and printer - Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type - "c:/programdata" - Go to the Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
