The document which is not included in the PDL file created by the PDL file conversion means 8 and thus created by the document editing means 6 is printed.

[0021]

The first effect is that, without putting a load on the network, the performance of the printer used for printing can be utilized and the W
It is possible to improve the print quality when printing an eb page. The reason is that a web page image can be output to a printer from a WWW browser as a high-resolution bitmap image matching the resolution of the printer,
Further, at that time, an instruction or the like for setting the printer in accordance with the printing conditions desired by the user can be added. In addition, the WWW server transmits a high-resolution bitmap image only when printing a Web page, and when displaying on a CRT screen, a low-resolution bitmap image adapted to the CRT screen is transmitted. This is because it is transmitted.

The second effect is the HTML of the WWW browser.
A constant print result can be obtained without depending on the performance of the interpreted part of the file. The reason is that the WWW browser does not interpret and print the HTML file, but receives data already converted to PDL by the Web page creation application from the WWW server and outputs the data to the printer.
