The only way from the Jeppessen Chart viewer is to display the chart as big as you can on your screen. Hold the ALT key and press PRINT SCREEN (ALT-PRINT SCREEN). This will copy the WINDOW. Now use imaging software (Paint shop Pro or Paint) and press Ctrl-V to paste the image. You can trim the excess from this image if you want it to look pretty.
Save each chart seperately on your flash drive and go down to reception and beg for a printer.
I hope you dont have too many to print - it might be quicker to have them faxed from someone.
Good luck!
