The document is printed with another DPI other than what is set in the Printer Preferences.
The document was created using the DPI settings of the default printer. Most applications (for example, Word, Excel, and so on) store the printer settings in the document.
For example, if the default printer was set to print at 600 DPI when the document was created, the 600 DPI setting is saved in the document. Because the Black Ice Printer Driver supports the 600 DPI setting, the application sends the document to the printer with the document’s DPI setting. To force the application to use the Black Ice printer settings, go to the Page Setup and change the DPI setting to the required value and save the document. If the application does not have a Page Setup option, or the DPI cannot be set, try the Print or Printing Options, select the Black Ice Printer, set the printer to the right DPI and save the document. In this case, the document is saved with the Black Ice Printer DPI settings.
