User guide Emulations141How are escapesequences used?Escape sequences are transmitted to the printer by your computersoftware via the printer driver. Experienced users and programmerscan also control the printer directly via control sequences, howeverbefore you start working with escape sequences and control codes,we recommend that you study the computer software manual.To enter control codes the Ctrl key and an ASCII character must bepressed simultaneously. For instance, by pressing Ctrl and J a linefeed is accomplished (it is required to output the character string onthe printer). More information concerning this topic is contained inyour computer software manual and the corresponding Program-mer’s Application Manuals (see section Programming manuals onpage 167).The selected emulation must correspond to the printer driverof your application program. Settings caused by ESCsequences remain valid, until they are switched off by anothercontrol code. All settings are reset to the original menu, whenthe printer is switched off.MTPL As the emulations do not cover the entire scope of your printer, anew printer language, which is adapted to this printer model, hasbeen created. Using MTPL you are able to optimize operation andhandling.MTPL can be used in connection with other emulations or can beused alone.Example in BASIC open “LPT1:” as #1width #1,255Text1$ = “10 characters/inch”Text2$ = “15 characters/inch”ESC$ = chr$(27)print#1,ESC$;"[4w";Text1$;ESC$;"[6w";Text2$;ESC$;"[4w";Text1$endExample in Pascal program cpi_example;uses printer;const ESC = #27;Text1 = “10 characters/inch”;Text2 = “15 characters/inch”;beginwriteln(lst,Esc,"[4w",Text1,ESC,"[6w",Text2,Esc,"[4w",Text1);end.Printout Nach Ablauf dieses Programmes wird folgender Text ausgedruckt:10 characters/inch 15 characters/inch 10 characters/inch
