LibreOffice uses the installed fonts of your system. In a text document you can select from all printable fonts. In an HTML document or in Web layout, only fonts that are visible on screen are offered. In spreadsheets and drawings you can select from all installed fonts.
In the Print dialogue box or the Printer Settings dialogue box, select the printer from the printers list box and click Properties. The Properties dialogue box appears containing several tab pages. This is where you can make settings that are used according to the PPD file of the selected printer.
On the Paper tab page, you can define the paper format and paper tray to be used as the default settings for this printer.
On the Device tab page, you can activate the special options for your printer. If your printer can only print in black and white, choose "greyscale" under Colour, otherwise choose "colour". If switching to greyscale leads to unfavourable results, you can also select "colour" under Colour and see how the printer or PostScript emulator applies it. Furthermore, on this tab page you can set the precision with which colours are described as well as the PostScript level.
To make the printer selected from the Installed printers list box the default printer, double-click its name or click the Default button.

Remember to create one separate print job for each fax, otherwise, the first recipient will receive all the faxes. In the Tools - Mail Merge dialogue box select the Printer option and then mark the Separate print jobs check box.
