Chapter 3 Application Development Information Application Development Information This chapter describes how to control the printer and gives information useful for printer application development. Overview The following is provided to use this product. ❏ The dedicated printer driver for Windows is available. The reprint function is implemented in the printer driver. The reprint function is not necessary to be imple- mented in the application since the printer driver performs reprint automatically when an error occurs (paper out, paper jam or ink missing dots occurs). (See "How to Use the Printer Driver" on page 154 for details.) ❏ Various utilities and user’s manuals are available.
❏ Dedicated sample program for TM-C3400 is available. Use this as reference to develop the application. ❏ EpsonNet SDK is available. This is used for EPSON network printer. On this product, this is used to check the network setting. The sam- ple program is available on EpsonNet SDK but it is not used for this product. 3 This product can not use the APD, OPOS, OPOS for .NET, and JavaPOS provided by Epson. Printer Driver The printer driver has the following functions and these are not necessary to implement in the application. ❏ Barcode and 2D symbol font is implemented. The barcode and 2D symbol font can also be printed using font replacement function for .NET environment.
The barcode and 2D symbol font must be set in advance on the printer driver to use this function. (See "Barcode Printing" on page 159 and "2D Symbol Font Settings" on page 172 for details of how to make set- ting.) On .NET environment, True Type font is specified to be replaced by barcode and 2D symbol font. The bar- code and 2D symbol can be printed by specifying replaced True Type font from the application. (See "Barcode and 2D Symbol Font Printing on .NET Environment" on page 178 for details about font replace- ment function.) ❏ The reprint function is implemented. The reprint preforms automatically from the page where the error occurs during printing.
Some conditions are required, see "Post-Printing Verification Settings" on page 21 for details. 129
