A novel method of printing including receiving printer setting information indicative of printer driver settings corresponding to a print request, and printing the printer driver settings along with a print job corresponding to the print request. Further, the printer driver settings may be printed only on a first page of the print request, on all pages of the print request, on a separate front sheet of the print request, and/or on a separate rear sheet of the print request. The printer setting information is further indicative of computer system information including, for example, a computer user name, a name of computer software used to make a file corresponding to the print request, a name of the file, a name of a printer printing the print request, and a printing time stamp. This computer system information may also be printed together with the printer driving settings. In addition, the printer driver settings include, for example, a printer paper source, an output paper tray, a layout setting, a collation status, a duplex setting, an orientation setting, a paper size, a scale rate, a positive or negative image, an original or mirror image, font information, watermark information, coloring information, and a print job waiting time and job queue schedule information. The present invention also relates to a printer and graphical user interface allowing a user to print the printer setting information on desired pages.
