What are the limitations of the printer exclusion field?
Release : 15.8, 16.0
The only hard limit to the printer exclusion field is 2048 characters per printer. Support has confirmed that at least 1,000 printers can be specified in the field and the product continues to work as expected.
Note that each printer value will be verified as being unique when the configuration is saved. Having a large list of printers may extend the time of the configuration save.
