How to print text files in Ubuntu Karmic

Ever since I upgraded to Ubuntu 9.10 "Karmic koala", printing text files has been a problem. They print out with normal line height, but in a super-wide font so I only get about 48 ugly characters per line.

Various people have reported the problem -- for instance, bug 447961 and this post -- but no one seemed to have an answer.

I don't have an answer either, but I do have a workaround. The problem is that Ubuntu is scaling incorrectly. When it thinks it's putting 10 characters per inch (cpi) on a line, it's actually using a font that only fits 6 characters. But if you tell it to fit 17 characters per inch, that comes out pretty close to the 10cpi that's supposed to be the default:

lpr -o cpi=17 filename

As long as you have to specify the cpi, try different settings for it. cpi=20 gives a nice crisp looking font with about 11.8 characters per inch. If needed, you can adjust line spacing with lpi=NN as well.

Update: The ever-vigilant Till Kamppeter has tracked the problem down to the font used by texttopdf for lp/lpr printing. Interesting details in bug 447961.
