Description

上記目的を達成するため、本発明にかかる印刷装置は、
ネットワークを介して接続された電子機器から供給された印刷データに基づいて印刷ジョブを実行する印刷装置であって、
前記印刷データは、一連のＰＤＬコマンドを含み、
前記一連のＰＤＬコマンドのそれぞれは、画像データを生成するコマンドと、画像データを生成しないコマンドと、のうちのいずれかに分類され、
前記電子機器から前記印刷データを受信する受信手段と、
前記受信された印刷データに含まれる一連のＰＤＬコマンドを、ＰＤＬコマンド記憶手段に登録するＰＤＬコマンド登録手段と、
前記ＰＤＬコマンド記憶手段に記憶されている一連のＰＤＬコマンドを先頭から順次実行することにより前記印刷ジョブを実行するコマンド実行手段と、を備え、
前記コマンド実行手段は、
前記ＰＤＬコマンドを実行する毎に、当該ＰＤＬコマンドが前記画像データを生成するコマンドであるか否かを判別し、
前記画像データを生成するコマンドである場合、当該コマンドの実行後、前記ＰＤＬコマンド記憶手段に記憶されている当該コマンドを、当該コマンドのサイズ分の、何も処理しないことを指示する制御データであるＮＯＰデータに書き換える、
ことを特徴とする。 In order to achieve the above object, a printing apparatus according to the present invention includes:
A printing apparatus that executes a print job based on print data supplied from an electronic device connected via a network,
The print data includes a series of PDL commands,
Each of the series of PDL commands is classified into one of a command for generating image data and a command for not generating image data .
Receiving means for receiving the print data from the electronic device;
PDL command registration means for registering a series of PDL commands included in the received print data in a PDL command storage means ;
And a command executing means for executing the print job by sequentially executing a series of PDL commands stored in the PDL command storage means from the top
The command execution means includes
Each time the PDL command is executed, it is determined whether the PDL command is a command for generating the image data .
In the case of the command for generating the image data, control data for instructing that the command stored in the PDL command storage means is not processed for the size of the command after the command is executed. Ru rewritten to NOP data,
It is characterized by that.

Claims

A printing apparatus that executes a print job based on print data supplied from an electronic device connected via a network,
The print data includes a series of PDL commands,
Each of the series of PDL commands is classified into one of a command for generating image data and a command for not generating image data .
Receiving means for receiving the print data from the electronic device;
PDL command registration means for registering a series of PDL commands included in the received print data in a PDL command storage means ;
And a command executing means for executing the print job by sequentially executing a series of PDL commands stored in the PDL command storage means from the top
The command execution means includes
If the PDL command to be executed is a command for generating the image data, after the execution of the command, the command stored in the PDL command storage means, the size of the relevant command, that no processing Ru rewritten NOP data is control data for instructing,
A printing apparatus characterized by that.

The command for generating the image data includes an image drawing command having a command portion representing a command for drawing an image and an image data portion representing image data,
The PDL command storage means includes command storage means for storing commands, and image data storage means for storing image data.
The PDL command registration means
When the PDL command included in the received print data is the image drawing command, the command portion of the image drawing command is converted into an internal command and registered in the command storage unit, and the image data of the image drawing command Registered in the image data storage means,
When the PDL command included in the received print data is not an image drawing command, the PDL command is registered in the command storage unit,
The command execution means includes
When executing the internal command, based on the internal command stored in the command storage means and the image data registered in the image data storage means, execute image drawing,
After execution of the internal command, the internal command stored in the command storage means is rewritten to NOP data which is control data for instructing not to process anything for the size of the internal command,
For commands that generate the image data other than the internal command, after executing the command, control that instructs the command stored in the command storage means not to process anything for the size of the PDL command Rewrite the data as NOP data,
The printing apparatus according to claim 1.

The internal command includes information for specifying a relative address and length of image data registered in the image data storage unit.
