As Don said, nowadays it's LOTS more lines of code, but that's OK. It is still good to be able to print out parts of code. Not like old assembly listings though. Maybe I need one of those tall portait oriented monitors ?

Esp for things like source code -- you don't want to have to scroll (much) to see The Big Picture. It's also helpful when viewing PDFs, etc. The problem with portrait orientation is the screen ends up too narrow for most other things. I experimented with a 30" landscape flanked by a pair of 24" portrait (they end up comparable dimensions, vertically). This was good if I wanted to have a PDF open on a "side" monitor and use the larger monitor for my main workspace. But, when there was no need for a PDF (or other "page display"), the tall skinny monitors on each side ended up underutilized; too narrow to do "real work". I ended up leaving a pair of 30" on my software workstation. I "work" on one and have the other available for supporting documents (schematics, datasheets, etc.) Install a PDF printer and route whatever you want to that device. Then, open the PDF and annotate it as needed. If you really want to have a piece of paper to scribble on, print the page(s) that are important to you. Just remember to discard them lest you find yourself with scraps of various "vintage" lying around.

That should work, even when there are wrapped lines (if not too many to destroy the layout). I don't know offhand if Word treats a FF character as a hard page break when it reads textfiles, but when it does you should be OK.

Use a2ps, should be available on any Linux system, the source should be available to compile it on Windows. It takes in raw ASCII text and puts out PostScript with all the formatting. It can also do portrait or landscape, and multiple pages/sheet, there are a ton of options. Jon
