処理中のプリンタースタック-ppdファイルの読み取りに失敗しました

Question

ネットワークプリンターをインストールする必要があります：Lubuntu 16.04にHP-LaserJet-Pro-MFP-m125nw。

HPLIPをインストールしました
プリンターに緑色のマークが付いたプリンターが表示されます
プリンターにジョブを送信できます

しかし、実際には印刷されず、ジョブは処理中としてマークされます。

ノート：

シンプルスキャンを使用すると、ドキュメントを正常にスキャンできます。
USBを使用してプリンターをインストールすると問題なく動作するので、ネットワークにプリンターをインストールしようとするときだけ問題があると思います

問題の原因とその修正方法を教えてください。

この警告は、hp-checkスクリプトにこのファイルを読み取る権限がないことを意味します。

次のように許可を変更するだけです（ターミナルを開きます）。

$ Sudo chmod 644 /etc/cups/ppd/HP-LaserJet-Pro-MFP-m125nw.ppd

すべてのユーザーに読み取り許可を与え、rootに対して読み取り/書き込みを許可します。

HPプリンターPhotoSmartを使用していて、同じ問題がありました.../etc/cups/ppd /に移動し、ppdファイルのアクセス許可を変更しました（rootアクセス許可が必要です）：Owner Root読み取りおよび書き込み-グループlp読み取り専用-その他いいえ、最後の許可を読み取り専用に変更しました。幸運を！
