If all you printers are set-up to have unique ports - e.g

LPT1
LPT2
LPT3
LPT7
...

why do not use textmerge to create a text file containing the text you want to print and then send this text to the printer

* <i>Here goes the lines for creating the txtmerge.dat file</i>
Set TextMerge TO <i>c:\temp\txtmerge.dat</i>
* <i>USE "\" instead of "?" and "\\" instead of "??", e.g: </i>
\Some text written on 
\\<< date() >>
Set TextMerge To
* <i>Finished creation of txtmerge.dat file</i>
lcTextToPrint = FileToStr('<i>C:\temp\txtmerge.dat</i>')
lnPrintHandle = FOPEN('LPT<i>1</i>', 2) &&Open Printer - let it be on port LPT1 for buffered write-only access
FWRITE(lnPrintHandle, lcTextToPrint)
FCLOSE(lnPrintHandle)
* Repeat above when necessary - why not move it to a UDP (user-defined procedure)?

Hope this is useful info to you
