A small number of PaperCut customers have reported to PaperCut Support that when printing with some Toshiba print drivers they recieve a popup (shown below) asking for a LDAP server. This prevents printing.
This functionality is not required in the print driver as PaperCut will already have authenticated the print job. You can turn this feature off by going to
Devices and Printer →
Right click on printer - Select Properties →
Device Settings tab and unticking
Update Automatically, then setting
Account Settings →
User Authentication →
Alternatively, we have had it reported that selecting “PaperCut” in the drop down list works in some environments. This is not a configuration that we actively support, but it may work for you.
