An important aspect to consider for assessment would be the requirement and usage of local printers. Usually, these would be relatively more expensive and inefficient than you realize. It would be pertinent to mention here that printers would only be servicing a single user and would rarely be networked.
The result would be making managed printing relatively more inefficient in a majority of business environments. It would not be wrong to suggest that they would be in dire need of unique cartridges that would be highly expensive to your printing cost and needs. In addition, the business would be prone to challenges faced in buying and inventory tracking.
