Pick this if...
- You run an in-plant print operation, departmental repro, or transactional shop doing 60,000-300,000 mono pages per month.
- You need 90 ppm Letter throughput on a known production chassis (the 4110/4590 platform).
- You inherited a 4590 and want to source supplies, finishing, or a parallel unit on the same workflow.
- You print short-run books, statements, manuals, and want SRA3 (12x18) for full-bleed work.
- You can take refurbished hardware — 4590 is end-of-life new but readily available refurb.
