Line Printer Daemon (LPD) 服務從 %1 列印工作，但該列印工作的列印格式不受支援。若用戶端上的印表機驅動程式是設定為使用此印表機不支援的列印資料格式，則會發生此情況。因此，可能無法正確列印文件。

The Line Printer Daemon (LPD) service received a print job from %1 in an unsupported print format. This can occur if the printer driver on the client is configured to use a print data type that is unsupported by this printer. The document may not print correctly as a result.
