How to print with Abiword
 

How I print a document with Abiword? How I configure my printer Epson LX-300?

I use a distribution named PupWin98 from PuppyLinux. The printer wizard is named Puppy Printer Wizard, but it no contain drivers for Epson LX-300.

It depends on the Linux distribution you use (does it have graphical tools to set up printers or do you use a web-interface or commandline, ...); for more help you need to tell us which distribution you use (Fedora Core, Mandrake, Debian, Ubuntu, ...).

It's not about Abiword, you'll have to configure a printing system (like CUPS, "Common Unix Printing System") which handles your printer; after this you'll just get a printer in the Print dialog's list of Abiword, just like in Windows for example. If you use CUPS, you can configure it from a web-interface by opening this address in your browser:

(I think, and hope, that it was that port)

But, if you use KDE or Gnome (common big desktop environments), you have a graphical tool to set up printers; in KDE it's in the menu under KDE Control Center; in Gnome it's a separate tool in some of the Settings menus. Plug in your printer, power it on, open up the CUPS/whatever-system-you-like-to-use configuration tool and choose your printer if/when it got detected.
