The printer in the sandwich shop - "CB's" - is still working. Phew. When I offered to fix the computer for them, I wasn't sure if I would do more harm than good. Luckily the problem was apparent from when I turned the machine on - somehow the printer port had become disabled and needed reenabling - a job that takes seconds. I then installed the printer driver and it was basically done. They left me in their plush downstairs kitchen (you can always tell a lot about a place from its kitchen) to get on with the task on my own. I enjoyed the chance to produce a comedy test print, which read:

I went downstairs at CB's and all I got was this lousy printout

Well, I thought it was funny.
