私はAndroidアプリを持っています。これは、サーマルプリンターからの英語の印刷で非常にうまく機能しています。コードは完璧です。しかし、問題は、アラビア文字やその他のUnicodeを渡すと正しく印刷されないことです。 。

問題はコードページにあります。文字列をバイトに変換するときに、アラビア語とUnicodeをサポートする別のコードページを試しました。アラビア語のログにも適切な文字列が表示されますが、印刷すると機能しません。

注：私のプリンターはアラビア語をサポートしており、コードページは32です。ユニバーサルプリンターソリューションが必要です。 EpsonSDKを使用していません。 ESC/POSコマンドを使用しています。

Answer 1

最も簡単なのは、EpsonSDKを使用することです。それがEpsonプリンターであるかどうかは関係ないため、USBデバイスのデバイスフィルターのベンダーIDのみがベンダー間で異なります。しかし、Star Micronicsやその他の100％互換機は問題なく動作します。独自のドライバーを作成したい場合、これは文字通り車輪の再発明を意味します。 ESC/POS 付録C、73ページをご覧ください。

アラビア語の場合、IBMコードページ CP864 である13コマンドを使用して文字テーブルESC tを選択する必要があります。シーケンスは次のようになります：\x1B \x74 \xD。また、出力はCP864としてエンコードし、UTF-16から変換して、プリンターが予期するコードページと一致するようにする必要があります。
