How long can I print this pattern? I saved the zip-file to my computer and unzipped the English.pdf file, but couldn't print it because there was not enough ink in my 4-colour printer. Will the zip-file stay in my computer forever or just a certain time?
there is no limit of time or downloads.
As long as you keep your account the pattern will stay.
Only if you wish to delete your account the pattern will be deleted, too.
