Epson TM-U220 Guide for right side up printing - Page 16

Confidential 2.2 Using DIP switch setting When your application uses a "paper cut" command (ex. "GS V") and doesn't use any forbidden commands, you can use this method. In this method, set the 2 DIP switches as described below: 1. Turn off DIP switch 1-2 (receive buffer: 4KB.) 2. Turn on DIP switch 1-1, TM-U220 keeps the right side up printing mode always. In this method, TM-U220 stores the all transmitted data from a host PC to the receive buffer always. When the TM-U220 prints the stored data, it requires a cut command (ex. "GS V")" to print stored print data. (Therefore, if your application doesn't transmit any cut command, your application have to be changed.) After the cut command is transmitted, the TM-U220 begins the storing again for next printing. Note: Don't apply this method for TM-U220 type D, because the printer doesn't have an autocutter. In this method, don't transmit the specific command "GS ( z nL nH 0 E." If you do so, the printed result isn't guaranteed. In this method, there are some forbidden commands just as there are when using specific command method. Check whether your application uses any forbidden commands or not (See "Forbidden/Restricted commands for right side up printing mode" on page 8.) If your application uses any forbidden commands, you have to change the application to use the right side up printing mode. 2.3 Forbidden/Restricted commands for right side up printing mode This section describes common information for the both methods "using specific commands," "using DIP switch setting." About the right side up printing mode, you should notice the Forbidden/Restricted commands, which can be divided into four command groups as described below. ❏ Forbidden command ❏ Restricted command ❏ Instant command ❏ Required to transmit at Beginning of the line command Note: "During right side up printing mode" means both "during DIP switch 1-1: ON" and "between the specific command "GS ( z nL nH 0 S" and GS ( z nL nH 0 E." 8 Rev.
