Title: Error: Printer ''XYZ'' UNKNOWN to NIPrint, DENYING PRINTING PROCEDURE

Error: Printer ''XYZ'' UNKNOWN to NIPrint, DENYING PRINTING PROCEDURE
This error is NIPrint telling you that you have not set up a printer named "XYZ" (or whatever you are getting on the local (NIPrint) Windows PC, or have set up a local printer but it is named incorrectly.

LPD/LPR (the protocol that NIPrint uses) requires 2 separate pieces of information (and 1 that may be required or may be optional) for each printer:
  1) An address
  2) A printer name (or queue)
  3) A user name (may be required, may be optional)

The address is needed by the sending host (the "LPR") to know where to send the print job.

The name is the name of the print queue - this is so that receiving system (the "LPD") knows which printer the print job is for (there may be more than one).

The user name is used for authentication if you have asked the LPD to authenticate by user name.

In this case, the LPR (the remote host) is sending a print job to the NIPrint system (if it was not sending the print job, you would not see anything in the trace) with a name of “XYZ” but NIPrint has either not been configured for a local printer at all, or NIPrint has been configured with a local printer that has a name that does not match “XYZ” (the name the remote host is sending the print job to). The name in NIPrint for the local print must match the name the host is sending EXACTLY - character for character.

You set up (or change) the printer name in NIPrint under "Configuration" -> "Local Print Configuration" -> "Add/(or Edit) Print button" -> "Printer Name".
