8.2.4. Driver Options
The Driver Options tab displays advanced printer options. Options vary for each print driver. Com-
mon options include:
• Send Form-Feed (FF) should be selected if the last page of your print job is not ejected from
the printer (for example, the form feed light flashes). If this does not work, try selecting Send
End-of-Transmission (EOT) instead. Some printers require both Send Form-Feed (FF) and Send
End-of-Transmission (EOT) to eject the last page.
• Send End-of-Transmission (EOT) if sending a form-feed does not work. Refer to Send FF above.
• Assume Unknown Data is Text should be selected if your print driver does not recognize some
of the data sent to it. Only select it if you are having problems printing. If this option is selected,
the print driver will assume that any data that it can not recognize is text and try to print it as text.
If you select this option and Convert Text to Postscript, the print driver will assume the unknown
data is text and then convert it to PostScript.
• Prerender Postscript should be selected if you are printing characters beyond the basic ASCII
set but they are not printing correctly (such as Japanese characters). This option will prerender
non-standard PostScript fonts so that they are printed correctly.
If your printer does not support the fonts you are trying to print, try selecting this option. For
example, you should select this option if you are printing Japanese fonts to a non-Japanese printer.
Extra time is required to perform this action. Do not choose it unless you are having problems
printing the correct fonts.
• Convert Text to Postscript is selected by default. If your printer can print plain text, try unselecting
this when printing plain text documents to decrease the time it takes to print.
• Page Size allows you to select the paper size for your printer such as US Letter, US Legal, A3, and
A4.
• Effective Filter Locale defaults to C. If you are printing Japanese characters, select ja_JP. Other-
wise, accept the default of C.
If you modify the driver options, click OK to return to the main window. Click Apply to save the
change and restart the printer daemon.
