"We need to have a spare copier since the only one that is functional is on its last leg." what does "on its last leg" mean?

Hello.... 這意思是說 唯一一台的copier 已經快不行了 快不行了.... 苟延殘喘 希望幫助到你 Mavis

’on its last legs’ = almost dead If something is getting old, worn out, outdated, or obsolete, you may use the phrase ’on its last legs’. My Toyota is a 1985 Tercel. It’s definitely on its last legs. I hope that helps. Cheers.
