No consumables in stock

My business has just stopped because my printer stopped. HP-SA decided to hold almost no stock of consumables, Got a R100k printer sitting here with 6 print heads, things pop like pop-corn. have spend R15000+ on print heads in the last 3 years and they decide it's not worth even keeping one in stock, I must wait 4 weeks. You want me to upgrade,, was thinking of a Z9,, not any more.
