"""Tests for the printer installer batch endpoint (/api/printers/install-batch).

The printer installer map lets a user pick printers on the shopfloor map and
download a .bat that installs them, grouping the same way the classic
installprinter.asp did (HP/Xerox -> universal PrinterInstaller.exe; other
printers with a .exe installpath -> that installer /SILENT; anything else ->
manual).
