TBarCode/SAPwin: History - Barcode DLL for SAP^®

• MSI based setup.
• Setup contains now 2 Barcode DLL versions (one for SAPlpd and one for SAPsprint).

• Some customers (rarely) had problems with the start up of SAPlpd (“Error in MFC application...“). A separate version of the Barcode DLL for SAPlpd (with different call stack format) fixes the problem.
• When reading the license data, the barcode.ini file was read only in the actual application path but not in the (alternative) Windows directory. This was fixed now.

• New Barcode Engine (TBarCode Library V7) with higher drawing precision and advanced possibilities to solve printer driver problems.

• A licensing problem (demo-barcode) with parallel processing by SAPsprint was fixed. May occur more often in Windows Terminal Server Environments.
• Depending on the used version, SAPsprint expects different return codes after bar code generation (implementation inconsistency). The actual service release 2 now implemented exactly the return codes expected by the latest revisions of SAPsprint and SAPlpd. Otherwise log error messages would occur with these versions.

• Default height was used, if "barcode.ini" parameter "direction=-1" was set.

• RSS - Reduced Space Symbology (all sub variants)
• EAN UCC Composite Symbology (all sub variants)
• MicroPDF417
• Enhanced error messages with indication of non-codable characters
• Demo text instead of horizontal line in unlicensed mode
• Shift parameter (barcode.ini) for vertical baseline adjustment
• Print control parameter M for convenient module width adjustment
• Tested SAPsprint and SAPWIN.dll support (access method G)
• Bar code generator is based on new TBarCodeLib V6

• The Log File shows the barcode.ini settings now.

• A problem with selection of the default check digit (P="1") was eliminated (showed an affect in "CodaBar 2 Width").

• Default-Setting "OptResolution" in the barcode.ini file is possible now.

• Printcontrols FN, FS, FW for individually bar code fonts.
• Default setting of the font in the barcode.ini is possible.

• Symbologies Codablock F, Pharmacode 1+2 Spur, RSS-14, Flattermarken
• Setup of font characteristics for EAN/UPC bar codes through barcode.ini file parameters.
• New Print controls: W=Bar Width Reduction; T=Text Alignment

• 2D Symbologies: the symbol height was influenced by the text flag (Print control A="1")
• BarSIMM-compatibilty for PDF417 Default X/Y Ratio was improved

• Adjusting of Default Guard Bar Width (barcode.ini), can help with problems with printer drivers (which don't print without horizontal line).

• If the barcode.ini file is not in the application path (but in Microsoft Win-NT directory), or is not found, the default module width was zero (instead of 0.5mm).

• Print control A=2 for printing the text above the bar codes.

• Wrong check digit in Code 39
• Exception when using FNC1 (print control %=)

• The print control P to switch on the check digit was uneffective (no check digits).

• When passing variables (printcontrol parameter V) a comma was not allowed in the data string, so it came to a "Variable Print Control Error". Now you can use "," in the data string.

• Emulation of BarSIMM default settings (module width, height...). If emulation is turned on, a higher compatibility to DIMM/SIMM printer extensions is reached.
• New print controls for German + Australian postcodes.

• License data was written to the registry and sometimes the license data couldn't be read correctly (security-problem).
• Data Matrix: in codes containing an odd number of digits a fortuitous character was inserted at the end.
• Float. Point Exception if B= Parameter are not in the print control.

• Print Control ... E="1" for encodation of escape sequences

• Special UPS-Mode, used for MaxiCode.

TEC-IT introduces version 4.0 of TBarCode for SAPLPD!

• Supports 2D symbology QR-Code for large amounts of data.
• In addition PDF417 can now be coded with up to 1500 characters by using extended Printcontrols.

• New Setup, based on TBC4 (ProdID="8"+9).
• QR-Code Print Controls.
• 2D support for up to 2500 characters (PDF417).

The following features were added:

• New supported bar code: Data Matrix
• The module width of bars and spaces is now adjustable in absolute units [mms/1000]. In previous versions the width was only adjustable in [pixels] - therefore the bar code width depended on the printer resolution. Also a default value for the module width can now be set in the barcode.ini file (setting: DefModWidth).
• Enhanced debugging features (e. g. sending a print control - barcode.ini setting BCText). Errors in the bar code (wrong print control, wrong bar code data) can be made visible on the printed document (barcode.ini setting: OnError).
• Better verification of syntax errors in print controls
• Symbol specific parameters for PDF417, MaxiCode and Data Matrix are supported now (e.g. EC-Level, Structured Append,...).

Corrections to V2.0:

• Bug Fix: a printing problem occurred always if the bar code data contained a comma (e.g. "123,45A"). This problem was corrected (cause: in this special case the data characters were interpreted as if they were part of the Print control)

Enhancements since V1.03:

• From V2.0 the 2D-Symbologies PDF417 and Maxicode are supported (with standard behavior).

Fixed: The error text is now displayed with a correct description
