CONSIDERATIONS
DISCLAIMER (DIRECTIVE 89/336/EC)
ATB1200 designed used component another finished good, intended placed market brought into service independently. system integrator using this item must assume responsibility Electro-Magnetic Compatibility (EMC) between this item environment, both emissions immunity/susceptibility. Particular attention should paid wiring connections between ATB1200 power supply, data source other parts user's system case special shielding and/or cable layout required meet applicable criteria. assist customers, Able Systems carried traceable pre-compliance tests popular Ap1200 printer, which uses variant ATB1200 ELM205-ST mechanism. results these tests indicate that printer mechanism controller electronics unlikely prevent compliance customer's equipment, follows: Since ATB1200 powered will only electrically connected within equipment, conducted emissions immunity relevant, consider that ATB1200 falls outside scope Regulations these regards. When fitted earthed steel case connected internal data source power supply, ATB1200 expected comply with requirements Directive respect radiated emissions immunity; "Section Earthing Arrangements ESD" below special information about ESD. EARTHING ARRANGEMENTS
standard ELM205-ST provision earth connection metal parts printer mechanism. order satisfy criteria when using this mechanism, system integrator must ensure that user cannot discharge themselves metal parts mechanism. This could achieved, example, preventing user from gaining access those parts, ensuring user discharged earth before gaining access them. variant ELM205-ST mechanism available (order number: ELM205-ST-VRF), which metalwork printer internally connected system power ground. this case, system integrator must ensure that sufficient power supply voltage filtering place cope with possible strikes. Please refer Able Systems more information required this. ADVICE
While system compliance remains responsibility system designer, Able Systems many years experience implementing mini-printer solutions. particular, recommended that screened cables used, that cables kept short low-impedance possible, that user accessible parts adequately earthed. Further advice available from Able Systems request.

OPERATING MODES
ELM205-ST printer mechanism fixed (parallel) print head with horizontallyarranged thermal elements. paper advanced stepper motor, printing takes place single each step paper. Each printed approximately square. printing speed density controlled according voltage head temperature. possible print partial lines isolation: such line remains buffer, will printed until flushed line terminator some following data. following data will printed next line. paper only through printer forward direction. Alternative printing modes, including graphics, invoked 'Escape' sequences. Control codes status report protocols described detail Programmers Guide, available separate document. DATA BUFFER
ATB1200 nominal byte buffer optimise throughput: this enables data received into buffer while previous lines being printed. buffer cleared data command hardware reset. partially full line will printed receipt appropriate control code, after programmable timeout delay. SPOOLING MODE
spooling mode data received stored, printed. This useful when printing needs suppressed during data transfer (for example mobile radio systems); when paper needs changed, cleared, buffer contains data. selected, buffer will automatically enter spooling mode paper condition; also enter spooling mode command from host. spooling mode exited command from host, paper feed button being doubleclicked. stored data will then printed out. CHARACTER PRINTING
Several character fonts supported, default 32-column character being formed from 24x10 matrix. standard IBM® character (Code Page 437) includes graphics characters, which extended link both axes where appropriate. character been modified include Euro symbol (`') position (128 Decimal), place usual capital with cedilla Text printed various combinations single double width, single double height, inverted, underlined, with other attributes. Text dot- addressable graphics mixed within line. GRAPHICS PRINTING
Various dot-addressable graphics modes supported, dots line. Refer Programmers Guide full details.

FEEDING PRINTING PERFORMANCE
Feeding speed dependent supplied voltage shown: Voltage Feed Print Speed (mm/s) Duty Cycle
Table Feed Speed Voltage
recommend that ELM205-ST should feed print continuously more than seconds without pause, order avoid stepper motor overheating. addition, after feeding printing, printer should allowed rest period defined Table 2above. example, operating from 5.0V power supply, feeding period seconds should followed rest period seconds, yielding active duty cycle (30s 30+20s). maximum possible print speed given voltage same feed speed that voltage. However, actual print speed reduce heavy printing required. Also, ATB1200 configured limit peak current requirement PSU. this case, ATB1200 slows print process automatically that peak current drawn from never exceeds pre-set limit. Please Programmers Guide contact factory more information.
