私はSATO GL408eプリンタに印刷しようとしています。私はUSBインタフェース経由でデータを送信しようとしていますが、そのためのコード例はありません。私はここからサンプルコードを使用しようとしました：http://support.microsoft.com/kb/322091しかし、それはエラーも印刷もなく実行されます。 SATOプリンターにデータを送信する方法を知っている人はいますか？CATのSATO USB印刷
ありがとうございます！

残念ながら、私はすでにことを検討しています記事。それは私のプリンタのコマンド文字列を構築するのに役立ちましたが、私はプリンタにコマンドを手伝ってくれません。しかし、試してくれてありがとう！ – kereberos
