subject: sending printer commands to a EPSON TM-300PA 40 column line printer
We are currently developing a POS application that requires a 40
column receipt printer. We have used the Epson TM-300PA with
our DOS version of the POS software with no problems sending printer
commands such as (full cut) (bold) (double size) etc.
Our new POS software is being designed in Paradox 10 using Windows XP
We have been able to design the reports we want to print, however we
cannot embed printer commands into the report that the printer will
reconigize as a printer command.
In paradox 3.5 DOS we would simply place a calculated field at the
bottom of the report and input '027i' and the printer would see it
as a (full cut) command and fire to cutter.
Other commands would be used to automatically open a cash
drawer etc.
In PARADOX 10 we are currently using the GENERIC TEXT/ONLY
driver in Windows XP. It has a command line entry that will cut at
the end of the every report and it does work, however I need to string
reports together and cut only one time at the end of the chain of reports.
Therefore I have to be able to send printer commands directly from the
PARADOX 10 report generator.
Additionally, in the PARADOX 3.5 DOS version I could also write
a script with the following code ie
SETPRINTER LPT2
PRINT '+++++SHIFT REPORT+++++++'
PRINT 'n'
PRINT 'n'
etc.
etc.
PRINT '027i' (the cut command)
and this code would print directly to the receipt
printer and cut on demand.
I have NO IDEA how to communicate DIRECTLY with the
receipt printer in PARADOX 10 like I did in PARADOX 3.5
How do I get printer commands like <1B>H<69>H or '027i' to the
printer where the printer will recognize it as a command.
Using the Paradox report generator I have tried using calculated
fields, text fields, data model fields and cannot get the printer
to reconize these fields as printer commands. The printer simply prints the text
'<1B>H<69>H' or '027i'
Any help would be greatly appreciated.
