CUU Cursor Up:
Executes Vertical Position Backwards (VPB). CUU exists
for backwards compatibility with older printers only. Use VPB instead
of CUU. Future printers may not implement CUU.
Source: Application Destination: Level 3 (outmoded command)
Description
See VPB.
DA Printer Attributes:
Requests the printer product identification. The
printer responds to the DA command by sending a Printer Attributes
Report (DAR). See DAR.
Use DA (generic response) for normal Print manager inquiries and
forward compatibility. Use DA (alias response) for backwards
compatibility with older printers.
It is recommended that you send this command with no parameter.
Although the DEC PPL3 parsing rules allow a parameter in any
control sequence, this command is traditionally sent without one.
