C1 STRING(100)
C2 STRING(100)
C1Width BYTE
C2Width BYTE
WordStart LONG
WordEnd LONG
Text1 CSTRING(1000)
MyPrinterDialog LONG
MyPrinterFF LONG
PrintDataAddr LONG
PrintDataLen LONG
EnumPtrcl EnumPrtClType
ReceiptQ QUEUE,PRE(ReceiptQ)
Line CSTRING(100)
END
Window WINDOW,AT(,,300,23),CENTER,GRAY
STRING('Printing
Receipt....'),AT(120,6),USE(?String1),FONT(,,COLOR:Red,,CHARSET:ANSI)
TEXT,AT(70,14,160,8),USE(Text1),BOXED,HIDE,FONT('Courier',,,,CHARSET:ANSI)
END
CODE
LOOP
IF GEN:ReceiptPrinter = '' OR ~GEN:ReceiptPrinterCols
MESSAGE('Receipt Printer Not Setup!')
SetupForm
CYCLE
END
BREAK
END
EnumPtrCl.Init()
MyPrinterDialog = 0
MyPrinterFF = 0
OPEN(Window)
C1Width = GEN:ReceiptPrinterCols - 12
C2Width = GEN:ReceiptPrinterCols - C1Width
?Text1{Prop:Width} = GEN:ReceiptPrinterCols * 4 + 1
?Text1{Prop:Text} = GEN:ReceiptMessage
DISPLAY
ReceiptQ:Line = CENTER('Store Number: ' &
GEN:StoreNumber,GEN:ReceiptPrinterCols)
DO AddReceiptQ
!Add any more lines needed here
!This is how I format for Item followed by an amount
C1 = RIGHT('Gift Card Number:',C1Width)
C2 = RIGHT(GIH:GiftCertNumber,C2Width)
ReceiptQ:Line = CLIP(C1) & CLIP(C2)
DO AddReceiptQ
!Add receipt text from setup file
LOOP i# = 1 TO ?Text1{Prop:LineCount}
ReceiptQ:Line = ?Text1{Prop:Line,i#}
DO AddReceiptQ
END
!Add blank lines required to force receipt to tear off
LOOP GEN:ReceiptPrinterBlankLines TIMES
ReceiptQ:Line = ' '
DO AddReceiptQ
END
LOOP x# = 1 TO RECORDS(ReceiptQ)
GET(ReceiptQ, x#)
IF ERRORCODE() THEN STOP(ERROR()).
PrintDataAddr = ADDRESS(ReceiptQ:Line)
PrintDataLen = LEN(CLIP(ReceiptQ:Line))
EnumPTrcl.DirectPrtBlock(MyPrinterDialog,GEN:ReceiptPrinter,PrintDataAddr,PrintDataLen,MyPrinterFF)
END!Loop
DO ProcedureReturn
AddReceiptQ ROUTINE
!Need FF if less than printers full col length
IF LEN(CLIP(ReceiptQ:Line)) < GEN:ReceiptPrinterCols
ReceiptQ:Line = ReceiptQ:Line & '<13,10>'
