Third-party (parallel) printing? (Epson)

» close window

The Question is:

We would like to replace the LA-310 connected to our Alpha Server 300 4/266
 through parallel port LRA0: with an Epson LQ-2170.  Just swapping the printers
 sort of works, except (a) there's quite a few seconds delay before printing
 begins and (b) the print
er doesn't seem to print the last few lines until you press the
 linefeed/formfeed button.  Hooking this printer to a PC booted to a DOS prompt
 and executing dir > lpt1: starts printing immediately and finishes completely.
  Could it be a VMS device setting
Alpha2> sh printer LRA0:
Printer LRA0:, device type LP11, is online, record-oriented device, carriage

    No Sixels           No Bitmapped            No Polled

The Answer is :

  Please move to a supported OpenVMS version and please apply any
  available parallel port ECO kit(s) for the OpenVMS version of
  the LRDRIVER driver in use.
  Existing topics include (440), (689), (976), (5031), (6329),
  (6869), and (7171).
  For the requirements of and assistance with the integration of
  third-party devices (including printers), please contact the
  device vendor -- there are several different protocol signaling
  schemes used for parallel printing, and the printer vendor will
  know the specifics of the particular printer.
  For information on the supported (Postscript) printers, please
  see the DCPS documentation.
  The OpenVMS Wizard normally recommends network-based printing
  over parallel-based printing.  Due to the various schemes for
  parallel printing, OpenVMS Wizard does not normally recommend
  the use of parallel printers.
