NOTES:
This peace of software is freeware and is not part of FiveWin.
The following code will let you print directly to the printer from inside
any Fivewin program, like OLD DOS days. Those users that need DOS printing
speed can use this class instead of the TPrinter class.
The use of the class is very easy and is very similar to the TPrinter class
of Fivewin, but we have not create any command to avoid the use of any
static vars.
This is a little sample of how to use the new class:
LOCAL oPrn
oPrn := TDosPrn():New("lpt1")
oPrn:StartPage() // optional
oPrn:Say(10,20, "This goes in line 10, column 20")
oPrn:EndPage() // optional
oPrn:End()
A little description of all the members of this class:
DATA:
cPort: Printing port, by default "LPT1"
cCompress: String for compressed mode, by default "15"
cNormal: String for normal mode, by default "18"
cFormFeed: String for EJECT, by default "12"
hDC: Printing file Handle (Internal use)
nRow: Current printing row
nCol: Current pringing column
nLeftMargin: Left margin, by default 0
nTopMargin: Top margin, by default 0
METHODS:
New(cPort) Constructor, no comment
End() Destructor, no comment
StartPage() Begining of a page, this method is optional
EndPage() End of page, this method is optional if there is only on page,
or you try to print in a row that is before the current one,
like it did happen with the SAY command
Command(c) Let you send any command to the printer without changing the
current row and col. The string to pass as a parameter should
content the ascii values of the command separated with commas,
for example, the command to reset Epson printers should
be: "27,69"
SetCoors(r,c) Let you change the current row and col is the equivalent of
SetPrc() of Ca-Clipper
NewLine() Increments the current row
Write(cText) Prints the string cText in the current row and column
Say(nRow ,; Prints the string cText in nRow, nCol
nCol ,;
cText )
SayCmp() The same as the method Say but prints in compressed mode and
the row is updated accordly.
NOTE:
At the end of this class is a little function call WorkSheet that will make
the job of DOS printing a lot easier.
Enjoy it!
