Printing in WLanguage

Overview

WINDEV, WEBDEV and WINDEV Mobile propose several print methods:

the report editor, that is used to create "Preset reports".
the print functions in WLanguage.

The report editor

The report editor is used to create printed reports (in report or label format) containing information coming from data files.

We recommend that you create the printed reports with the report editor rather than with the WLanguage functions.

The reports created with the report editor are not available.

The print functions in WLanguage

However, for very specific development work, the report editor may not allow you to create the requested reports. In this case, you must use the print functions of WLanguage.

Caution: This chapter describes the principle for printing in WLanguage.

Principle for printing in WLanguage

The steps for printing in WLanguage as are follows:

Step 1 (optional): Configuring the print parameters
Step 2 (optional): Creating the print fonts (optional)
Step 3: Printing the characters, lines or images, and end of print.
Step 4: Starting the print.

Limitations

Limitations for printing from a Terminal Mobile (Pocket PC)

The limitations for printing from a Mobile Device (Pocket PC) are as follows:

only the printer fonts are available for printing.
If the font used is not available, the closest font will be used.
PCL printer.

Tips: To speed up your prints, limit the number of graphic options (border lines, grid, ...) that slow down the prints and that use a lot of printer memory.

Important

To directly print on a printer connected to the server, a specific configuration is required. See Configuring the server to perform a print for more details.

Printing in Linux

Only the prints in PDF format are available in Linux.

A specific configuration is required to print in Linux. See Printing in Linux for more details.

Versions 18 and later

Printing in the iPhone/iPad applications

Only the prints in PDF format are available in iOS.

If necessary, the created PDF file can be printed from the device by iPrintPDF. This function allows you to use the native system window to configure the file print.

New in version 18

Printing in the iPhone/iPad applications

Only the prints in PDF format are available in iOS.

If necessary, the created PDF file can be printed from the device by iPrintPDF. This function allows you to use the native system window to configure the file print.

Versions 19 and later

Printing in the Android applications

Only the prints in PDF format are available in Android.

By default, if iDestination is not called before starting a print in PDF format, a "document.pdf" file will be generated in the directory of application files.

If you must open the PDF document generated by the print functions with an external application (by using ShellExecute for example), this document must be found on the external memory of the device (sdcard for example) in order to be accessible by the other applications.

Example:

iDestination(iGenericPDF, CompleteDir(SysDirStorageCard()) + "document.pdf")

If necessary, the created PDF file can be printed from the device by iPrintPDF. This function allows you to print the file by using the Cloud Print service of Google.
