I have recently purchased an officejet 4620.
We want to print in greyscale so I changed the settings to do so. However the printer seems to just ignore those settings and prints in colour as well. We have also tried to print 2 to a page and the printer ignores this as well. When i went back to the settings they were still set to greyscale. It would seem to me that the setting changes are not being communicated to the printer.
I am connecting via wifi to the printer.
Many thanks for the help
