Yes I also read the comment that way. The inkjet printer remark presumably refers to benchtop DNA synthesis machines which have been commercially available for a while now. (The linked article mentions the possibility of buy-back programs for old machines that don't enforce any restrictions.)
I guess it's not a bad idea to put basic hurdles in place but it would be a serious mistake to see this as any sort of comprehensive preventative. DNA just isn't difficult to manipulate.
The thing is DNA just also isn't dangerous. It's fragile and everything in the environment destroys it - as noted it's literally a everything else which is the hard part.
This reeks of the Longtermists getting their influence into government. They were doing an entire round on YouTube about a year ago.
