Why not?
I still format my code to an 80 column width.
I can still use `pr` to paginate my source for printing, and use `enscript` to produce a PostScript document of it, then `ps2pdf` to convert that to PDF, then I can spool that PDF to any printer.
And, on my home network, I have a HP LaserJet 2300dn and I can actually just shove the plain text output from `pr` straight to the JetDirect port on 9100/tcp.
What exactly is the obstacle that's preventing you from printing out your source code?
But on the odd occasions that I do, I print the code with a monospaced font directly to .PDF.
I then transfer that .PDF to a large-format Kindle (like the Scribe).
When I don't need that anymore I delete it from the Kindle, but retain a copy of the .PDF for future use if necessary.
