The US intelligence apparatus doesn’t do this. The OPM does.
As per your second paragraph and many other comments. I agree. It is hard to avoid it being politicized at any step of the process. Everything interview would have to be recorded. Copies of all reviewed records would need to be kept. Adjudicators would need heavily redacted transcripts of the records and interviews.
Unless you REALLY need color, just buy a Brother BW laser printer. Toner doesn’t dry up. It is all but guaranteed to be the cheapest option. I bought the scanner BW laser printer combo like 8 years ago for $130.
