Visual Basic, Need to send a command directly to printer (Eltron Card Printer)

Need to send a command directly to printer (Eltron Card Printer)

Peter Marque #1 / 4	Need to send a command directly to printer (Eltron Card Printer) Hi I am working on an app that sends commands to an Eltron P300 Card Printer to encode magnetic swipe cards. The progamming manual offers a full range of the commands and parameters required, but I am having problems with certain required characters (esc, space and return). The manual suggests sending the commands directly using DOS (e.g COPY filename LPT1) I have tried in VB6 using FileCopy "c:\CommandTest.txt", LPT2 which seems to be received by the printer (as the led's on the front panel of the printer light up), but nothing else is happening. an example of the code being sent is: (esc)&B(space)2(space)123456(return) (esc)&E*(return) the above command basically writes "123456" to track 2 of the magnetic strip of a card. The thing I am stuck on is the correct characters to use for esc, space, and return. Any suggestions would be greatly appreciated TIA - Peter

Michael William #2 / 4	Need to send a command directly to printer (Eltron Card Printer) Escape = 27 Space = 32 Return = 13 By the way, have you tried writing driectly to the printer port from Visual Basic: Open Printer.Port for Output as #1 Print #1, "whatever"; etc Mike Quote: > Hi > I am working on an app that sends commands to an Eltron P300 Card Printer to > encode magnetic swipe cards. > The progamming manual offers a full range of the commands and parameters > required, but I am having problems with certain required characters (esc, > space and return). > The manual suggests sending the commands directly using DOS (e.g COPY > filename LPT1) > I have tried in VB6 using FileCopy "c:\CommandTest.txt", LPT2 which seems to > be received by the printer (as the led's on the front panel of the printer > light up), but nothing else is happening. > an example of the code being sent is: > (esc)&B(space)2(space)123456(return) > (esc)&E*(return) > the above command basically writes "123456" to track 2 of the magnetic strip > of a card. > The thing I am stuck on is the correct characters to use for esc, space, and > return. > Any suggestions would be greatly appreciated > TIA - Peter
