Cloud Print Connector 1.2 Overview

The Lasernet Cloud Print Connector 1.2 includes the option to print LNEMF files.

The benefit of LNEMF files is that they make cloud printing printer-independent. The installation of different printer drivers (brands) on the Lasernet server is not required, as it was in the legacy version of the Lasernet Cloud Print Connector.

The following formats are supported through Cloud Print Connector:

Installation

Enabling the print process of the LNEMF files requires downloading and installing version 1.2 of the Lasernet Cloud Print Connector.

The Lasernet Cloud Print Connector can be downloaded with the help of the Download menu available on the Printers page (Lasernet > Setup > Lists > Printers).

Supported Printer Properties

Printer properties can be defined and passed to the Lasernet Cloud Print Connector through a Printing Contract. The supported printer properties are as follows:

• FormName

• Orientation (landscape or portrait)

• PaperWidth

• PaperHeight)

• Scale

• Copies

• PaperSource (number, or a paper source, such as "Tray 1")

• PrintQuality

• ColorMode (color or monochrome)

• DuplexMode (simplex, horizontal or vertical)

[1] The printer supports it.

[2] The printer supports it, but it looks like the settings are only used for rendering and not actually being sent to the printer.

Example: if there are two copies, two prints are made. However, the printer only sees one copy.

[3] The printer requires that we either parse the RAW data, or Lasernet splits the commands into pages, for instance, create an LNRAW contract like LNEMF.

[4] The printer expects settings to be part of data (commands), so settings are ignored.

[5] Print job ID is not returned, so it requires additional work.

Lasernet Default Configuration Application

Our Lasernet Default configuration includes the setup for the Lasernet Cloud Print Connector. Details on this setup are described in this guide.

Global JobInfo EnableLNEMFPrinting

A global JobInfo EnableLNEMFPrinting on the Server determines whether RAW or LNEMF must be used for printing.

When using LNEMF (EMF) printing, the EMF to RAW module is skipped, and documents can get passed directly from a print sheet (Form) into the Azure Storage Printer (storage used by Cloud Print Connector).

The LNEMF document is encoded (Base64 Encode) before passing to the Azure Storage Printer output module.

Printer Contract

The Azure Storage Printer output module contains JobInfo xmlPrinterSettings in Pre JobInfos, which passes details on how the file should be printed.

• xmlPrinterSettings: Printer properties such as the Orientation, Paperwidth, Paperheight, copies, etc. This JobInfo contains the Printing Contract values.

Scripts

EnableLNEMFPrinting is used within the Lasernet Connector functions script, function setOutParameters:

// Need to Base64 encode JobData when printing allowed LNEMF

else if ((prefix.toLowerCase()=='Output'.toLowerCase() ||

prefix.toLowerCase()=='CustomOutput'.toLowerCase()) &&

job.getJobInfo('PrinterType').toLowerCase() == 'Lasernet Cloud Print Connector'.toLowerCase()&&

job.getJobInfo('DataFormat').toLowerCase() == 'EMF'.toLowerCase() &&

job.getJobInfo('EnableLNEMFPrinting').toLowerCase() == 'Yes'.toLowerCase()) // when main file

{

                   if (job.getJobInfo(prefix+'JobDataEncoded').toLowerCase() != 'Yes'.toLowerCase())

                   {

                                      logger.logEvent(0, 'Base64 Encoding main');

                                      job.setJobData(Base64.encode(job.getJobData())); // double encoding?

                                      job.setJobInfo(prefix+'JobDataEncoded', 'Yes', true);

                   }

}

logger.logEvent(0, 'EnableLNEMFPrinting=' + job.getJobInfo('EnableLNEMFPrinting'));

// Setting document index to next

getSetIndex(prefix, documentIndex);

                  

    // Setting document index to next

    getSetIndex(prefix, documentIndex);
