I posted about this before but am now looking to give away my HP 44" z3100ps. It has worked really well for me for 10 years but recently seems to have dropouts in the heads.
I did several head replacements but it now the printer is asking for more head replacements and I'm guessing there may be a larger issue.
If you want it and want to try to get it back on it's feet (which might be easy!) then you'll have a full functioning 44" printer!
Obviously you'll need to come pick this up. We're on first floor level so it's easy to roll into a Uhaul
