This is how I transfer files across to my PC from my A1200
1. buy asecond cheap compact flash card (1 GB is plenty)
2. buy a pcmcia compact flash adaptor
3. install fat95 on A1200 (aminet) to mount an format the compact flash drive for use on the A1200.
4. Open the .iff file in Personal Paint (aminet)
5. With PPaint convert it to .png or .gif or .jpeg (for ham8) and save to compact flash card (use 8.3 filenames)
6. put compact flash in PC card reader.
7. Open file in PC and print from PC. (no need to worry about finding amiga compatible printers, drivers, interfaces)
You could even just take your compact flash card to photo printing place.
On my A4000 I have and IDE to compact flash adaptor screwed in where the second floppy drive bay is, which makes it convenient to plug the CF card in and out ( power down and re boot focourse)
Or, if he has a network, a PCMCIA network card for the A1200 and transfer files that way. For example, my PC (which gets used for a lot of developer resources and tools, SVN repository etc) hosts a share that all my Amigas mount as a drive on boot up. It's faster than you might think and you don't have to open up any machines.
