プリンター出口モジュールのサンプル (sampprnx.cbl) は、デフォルトでは製品インストール ディレクトリの \src\enterpriseserver\exits サブディレクトリにあります。このサンプルでは、単に各行を取得し、COBOL ランタイム システムの印刷ルーチンを呼び出してその行を印刷します。
プリンター出口は COBOL で記述されている必要はありませんが、sampprnx の指定どおりにパラメーターを処理する必要があります。これらのパラメーターは、cascbprn.cpy コピーブックで定義および記述されています。COBOL プリンター出口は、非メインフレーム方言、つまり CHARSET(ASCII) を使用してコンパイルする必要があります。また、これらのプリンター出口は、.int、.gnt、または .dll としてビルドしなければなりません。
