Warning about Operating System Updates...
We highly recommend you check with your printer manufacturer for a full, up-to-date driver that is compatible with Mojave before updating your Mac OS.
As with all software updates, it can often take a couple of months before the drivers are updated, particularly for older printer models. Updating before a full driver is available may result in printer and colour management issues due to the basic Mac driver having reduced functions.
PermaJet will not be held responsible for any issues rergarding this - please speak to your printer manufacturer for further guidance and advice.
