Hi All
I use code below to print to ticket printers (POS). It works fine on WINDOWS XP but in WINDOWS VISTA nothing appens!! Any security configuration...
Any ideas will be great.

Thank's in advance,
NPedro

********** SAMPLE CODE *************
nHANDLE = FOPEN("lpt1.dos", 2)
IF nHANDLE>=0
=FWRITE(nHANDLE,"sample test")
=FCLOSE(nHANDLE)
ENDIF

********** END CODE **************
