Keep an eye out for a new laser sale. Sometimes you get the new laser with a half cattidge cheap.
That is what I intend to do when my Xerox color laser quits or I run across a good deal. BlackFriday/CyberMonday prices are ridiculously low on some of them. I sort of am looking for a color laser duplex.
However, I have heard that new printers (inkjets and lasers) only have partially filled ink/toner cartridges.
I use my Xerox at home (I am retired) and print only occasionally. I am still on the original cartridges -- after 8 years.
