PSDK:
If the Command parameter is PRINTER_CONTROL_SET_STATUS, pPrinter must contain a DWORD value that specifies the new printer status to set. For a list of the possible status values, see the Status member of the PRINTER_INFO_2 structure. Note that PRINTER_STATUS_PAUSED and PRINTER_STATUS_PENDING_DELETION are not valid status values to set.
If Level is 0, but the Command parameter is not PRINTER_CONTROL_SET_STATUS, pPrinter must be NULL.
