UEMdev,
We seem to be exceptional at finding strange new problems.
With the error pasted above, it is always the exact same failure with that printer - error 3012, tried 21 times, waited 21000ms. And yes, completely consistent in my testing (probably 20 logons) when the printers common setting is enabled. Since you asked that, it made me think to try another printer. Similar but slightly different results.
I first logged in with the printer common settings enabled and got:
2018-04-03 12:32:39.999 [ERROR] Error 3012 trying to map printer '\\printserver\Flex-Print' (tried 21 times; waited 21000 ms) ('Flex Print.xml')
2018-04-03 12:34:43.654 [INFO ] Successfully mapped printer '\\printserver\PlotterHP6200' ('Plotter.xml')
2018-04-03 12:34:43.654 [DEBUG] Processed 2 UEM printer mappings (1 successful, 1 error)
I logged out, didn't change anything (common setting still enabled), and logged in again (twice) and got:
2018-04-03 12:46:28.414 [ERROR] Error 3012 trying to map printer '\\printserver\Flex-Print' (tried 21 times; waited 21000 ms) ('Flex Print.xml')
2018-04-03 12:46:51.274 [ERROR] Error 10 trying to map printer '\\printserver\PlotterHP6200' (tried 21 times; waited 21000 ms) ('Plotter.xml')
2018-04-03 12:46:51.274 [DEBUG] Processed 2 UEM printer mappings (2 errors)
So it seems as if once the printer is picked up by the UEM common setting, it will then fail to map. Though the new one got a different error number.
I disabled the common setting and got:
2018-04-03 12:56:55.596 [INFO ] Successfully mapped printer '\\printserver\Flex-Print' ('Flex Print.xml')
2018-04-03 12:56:55.596 [INFO ] Set printer as default
2018-04-03 12:57:22.532 [INFO ] Successfully mapped printer '\\printserver\PlotterHP6200' ('Plotter.xml')
2018-04-03 12:57:22.532 [DEBUG] Processed 2 UEM printer mappings (2 successful)
And yes, the drivers for both of those printers are in the base image.
