I'm using imagemagick to convert the JPEG picture from the camera but can't manage to transform it the right way so that it prints well on a BTP-R580.\r\nThe resulting printed picture is only Black and White. I was wondering how to print a grayscale picture ?\r\n\r\nThanks!!"},"comment":{"url":"https://api.github.com/repos/song940/node-escpos/issues/comments/370254286","html_url":"https://github.com/song940/node-escpos/issues/113#issuecomment-370254286","issue_url":"https://api.github.com/repos/song940/node-escpos/issues/113","id":370254286,"user":{"login":"Clem-","id":1936021,"avatar_url":"https://avatars0.githubusercontent.com/u/1936021?v=4","gravatar_id":"","url":"https://api.github.com/users/Clem-","html_url":"https://github.com/Clem-","followers_url":"https://api.github.com/users/Clem-/followers","following_url":"https://api.github.com/users/Clem-/following{/other_user}","gists_url":"https://api.github.com/users/Clem-/gists{/gist_id}","starred_url":"https://api.github.com/users/Clem-/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Clem-/subscriptions","organizations_url":"https://api.github.com/users/Clem-/orgs","repos_url":"https://api.github.com/users/Clem-/repos","events_url":"https://api.github.com/users/Clem-/events{/privacy}","received_events_url":"https://api.github.com/users/Clem-/received_events","type":"User","site_admin":false},"created_at":"2018-03-04T19:03:09Z","updated_at":"2018-03-04T19:03:09Z","author_association":"NONE","body":"It seems that it's just an matter of \"monochrome\" picture.
