TM-U220 Technical Reference Guide 6.2.2 Cutting Method The TM-U220 (Type A, B) has auto cutting with partial cut or full cut method. These methods are switched by user operation. (See "3.4.7 Select Autocutter action (3-28 page)" for detail.) However, the partial cut method is little different from the TM-U300. The TM-U300 can select the partial cut method from Driver or ESC/POS command control. There are two partial cut methods, one is three points left method, the other is one point left uncut. 6.2.3 Dimensions Some dimensions ofthe TM-U220 are smaller thanthose of the TM-U300 except Type D. Therefore, the TM-U220 can be installed in the same space as a TM-U300. Dimensions (W x D x H) Type A: Type B: Type C: Type D: TM-U300 170 x 288 x 183 170 x 253 x 148 158 x 295 x 145 158 x 235 x 125 TM-U220 160 x 286 x 158 160 x 248 x 139 -160 x 248 x 139 See "1.7.1 External Dimensions and Mass (1-17 page)" for details. 6.2.4 Receive buffer size This topic is for serial model. The receive buffer size of the TM-U220 can be changed as shown in the following table. Product Receive buffer capacity TM-U300 40 bytes (DIP SW1-2 is On) Condition of buffer full Condition of release full state Byte number from buffer full to release full state Buffer space is Buffer space is 10 bytes 10 bytes 20 bytes TM-U220 (ANK: DIP SW1-2 is Off) 1K bytes (Multilingual: DIP SW1-2 is Off) 512 bytes 40 bytes (DIP SW1-2 is On) Buffer space is Buffer space is 10 bytes 16 bytes 26 bytes (Regardless of MemSW8-7) 4K bytes (DIP SW1-2 is Off) (default) Buffer space is Buffer space is 128 bytes 128 bytes 256 bytes (MemSW8-7:OFF) (default) Buffer space is Buffer space is 10 bytes 128 bytes 138 bytes (MemSW8-7: ON) Note: The receive buffer of TM-U300 may cause lost data at bufferfull state when there is no FIFO setting, or the FIFO setting is larger than 10 bytes. However, the TM-U220 will have enough remaining receive buffer space to prevent data loss at bufferfull state when DIP SW1-2 is Off regardless of the setting of MemSW 8-7. Rev.
