POS like Print a line at a time.

rbuser

Some thing like when a record is appened into the table then immeadiately
print that record content like in a POS invoice, also it has to check for
the page break and other normal routine of a report.

Any clues ? Sample code will be helpful and appreciated.

Thanks in advance,

The RB report engine checks for page breaks based upon the page size that
you specify for the report. The equivalent to a line in RB is a detail band.

If you need print each record with a call to Report.Print, then you could
try creating a report layout that has a page size that is essentially one
record tall. Note that each page will generate a page break. If this is an
issue, then you will need to create a custom TmyPosPrinterDevice class that
is essential a copy of TppPrinterDevice that does not issue the
Print.startpage, Printer.endpage commands. See RBuilder\Source\ppPrnDev.pas.
To use your TmyPosPrinterDevice class you will need to create an instance of
it at runtime, assign its Publisher property to Report.Publisher and call
Report.PrintToDevices. See demos 123 and 124 in
RBuilder\Demos\Reports\Demo.dpr.

Thanks.
But I hope there is something easier with some exact sample code, after all
this is a very basic and essential feature most of the business application
would insist. RB should build some thing to solve this sorts of problems
with ease.

Thanks.
