Cloud Print Connector now includes the option to print LNEMF files which do not require installing different printer drivers (brands) on the Lasernet server.
The following formats are supported through Cloud Print Connector:
Format | Description |
|---|---|
Used when re-printing documents from the Lasernet Archive or when printing attachments. | |
RAW | When using the EMF to RAW (Cloud Print Driver) module in Lasernet – requires the different printer drivers/brands to be installed at the Lasernet Server. |
LNEMF (EMF) | Used when printing directly from the Form/Print-sheet and does not require the different printer drivers/brands to be installed at the Lasernet Server (printer independent). |
Global JobInfo
An additional global JobInfo is introduced in the standard demo setup to identify whether RAW or LNEMF is to be used for printing.
EnableLNEMFPrinting
Printing the LNEMF (EMF) files requires adjustments to the Lasernet configuration.
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).
It is important to encode (Base64 Encode) the document (LNEMF) before parsing it to Azure Storage Printer. ZIP is not currently supported when printing the LNEMF files, but it would significantly reduce the file size once introduced.
Such information as Orientation, Paperwidth, Paperheight, copies, etc. is added to Pre JobInfos at Azure Storage Printer which contains the contract for Cloud Print Connector.
Printer Contract
The printer contract value is found in Pre JobInfos > xmlPrinterSettings > Value:
<PrinterSettings xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">

<a:Key>PaperSource</a:Key>

[1] If the printer supports it.
[2] But looks like the settings are only used for rendering and not actually being sent to the printer.
Ex.: if copies are 2, then two prints are printed, however, the printer only sees one copy.
[3] Requires that we either parse the RAW data, or Lasernet splits the commands into pages, i.e. 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 requires additional work.
Scripts
EnableLNEMFPrinting is used within the LAC function:
}
// Need to Base64 encode JobData when printing allowed LNEMF
else if ((prefix.toLowerCase()=='Output'.toLowerCase() || prefix.toLowerCase()=='CustomOutput'.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);
}
Prerequisite
Enabling the print process of the LNEMF files requires downloading and installing a new version of Cloud Print Connector which is included in Lasernet Connector for Microsoft Dynamics 365 Finance and Operations version 6.7.0 (version 1.2.0.0).
Cloud Print Connector can be downloaded with the help of the Download menu available on the Printers page (Lasernet > Setup > Lists > Printers).
Please click here to download the package.
