Logistical problems: Buying paper and having it delivered to your printer is similar to a purchasing agent buying component products and delivering them to another manufacturer instead of finding a manufacturer that can deliver the product complete.
Any time you get involved with supply components, you run the risk of something going wrong in the transaction. This is the No. 1 reason I recommend not buying the paper separately. Potential problems could include: wrong paper, late delivery, wrong quantity and bad quality. At this stage, any one of these problems most likely will cause a delay in your print job. A delay can be very costly in downtime, causing you to miss your printing window or even a critical mail date on time-sensitive materials.
