Publish on Deman is a term which is mistakenly used to refer to publishing using print on demand (POD) technology. The increasing difficulties for authors to be published through traditional methods combined with the low cost of POD has caused the technology to be associated with subsidy publishers and vanity presses. Vanity and subsidy presses often intentionally confuse the terms "publishing" and "printing," the publisher being the entity that pays for the printing and dissemination of literature or information.
