Late to the thread but I owned a HP DesignJet 1050C until recently. It's 
similar to what was on the curb in Arlington, MA I believe?

They're beautiful machines. The ink carts can be had expired and will run. 
The drive belt will degrade and turn to mush after ~14 years or so 
depending on where it's stored. Replacements are $20 from eBay.

The ink carts and heads run $900 new but used I used to get them dirt 
cheap via ebay, always expired by 10 years or so. Yellow is the first to 

Standard inkjet white paper from ebay is like $20 a roll for linear feet 
at 36" wide.

My machine was 4 color not 6 color (no pastels.) Used it to print cheap 
signage for a Makerfaire in Norfolk, signage for an arcade and video game 
music event called MAGFest in the DC area and a few other events. I sold 
it because I wasn't as involved in running events + there is one at the 
local makerspace. Plus needed room for more arcades/pinballs.

New machines might lock out expired ink carts though.

I have owned pen plotters in the past as well, they are fun to watch.

But the HP designjets are cool machines. But physically somewhat large as 
there is a lot of extra room on the left and right of the print area 
compared to similar machines from Epson.

There are videos on youtube on swapping things like the ink delivery 
system and the drive belt. I feared actually doing to work to replace the 
drive belt but really it took like 30 minutes after watching the video and 
having torx nearby.
