Valid from List & Label 15By default, List & Label tries to determine if a printer exists at all on the system before trying to initialize it. With network printers, this is usually benefical if the printer used for the project is not accessible from all workstations. If the printer would be initialized nevertheless, 20-30 second timeouts would considerably slow down your application. You should not switch off the pre-checking in this case.
However, if you can make sure that the printer is accessible for everyone, you can disable the check by setting LL_OPTION_NOPRINTERPATHCHECK to "True". This will yield a slightly better performance. The default for this option is "False".
Note the hints on "LL_OPTION_NOPRINTERPATHCHECK" in the programmer's reference.
