This FAQ assumes that you are using the latest version of GNU Enscript, there are many old bugs and misfeatures but many of them have been fixed for the latest version. For on-line information about the latest version, bugs, features, etc. please, check the GNU Enscript WWW home at URL: http://www.iki.fi/~mtr/genscript/.
First, you will need a PostScript font (.pfa or .pfb) which has those line drawing characters. This is the trickiest task since these fonts are really rare. Once you find one, you must make it available for enscript (see file README for details) so it can be downloaded to the printer.
Since these suitable fonts are so rare, the ibmpc encoding do not contain mappings for those line drawing characters, this means they won't print if you use the ibmpc encoding. You must rely on the font's build-in encoding and print your files with option `-X ps' or `--encoding=ps'.
Manolis Lourakis (lourakis@csd.uch.gr) has written a document that describes how this can be done. It can be found from URL:

No, everything is ok but the problem is that Adobe's default Courier font does not have characters named: Aogonek, Lcaron, Sacute, Tcaron, Zacute, ... (those 44 missing characters) so enscript can't print them. You can solve this if you have a courier (or whatever) font that has those missing characters. One good canditate is courier font distributed with the X distribution, it is called cour.pf{a,b} and should be found from all good FTP sites.
To solve this problem, you must:
$ ls fonts
