With 800 strips you can print non-stop for about 7 hours (3 photos per strip), this will very rarely run out for parties up to 150 people, if this does happen exceptionally, rest assured all photos are always stored digitally even if the printer is empty. All photos will be emailed after the party. Unlimited printing does not exist, unless of course you replace the paper and ink roll when it is empty. Extra paper rolls can be requested in advance, (e.g. events of several days) make sure that someone is always present upon delivery who can get an explanation of how to replace the paper safely! Optionally we can provide a printer with 1400 strips.
