Dear Greeny:
In your command file, create a variable like:
SET VAR gPrinter TEXT = NULL
SET VAR gPrinter = (CVAL('Printers'))
(CVAL('Printers')) returns the current windows default printer. If it is
NULL then the user doesn't have a default windows printer installed. In
your printing block of code, you could do something like this:
IF gPrinter IS NULL THEN
PAUSE 2 USING 'No printer installed ... Report will not print.' +
CAPTION 'Warning' AT CENTER CENTER
ELSE
OUTPUT PRINTER
PRINT reportname ...
OUTPUT SCREEN
ENDIF

Subject: printer driver detection
Greeny question,
What documentation or which website, or any input on how to
detect a printer driver from a computer using rbase ?
I have a snipet of rbase code that prints the report but
when a computer that doesn't have any "printer driver installed"
run the instance of print snipet it will cause the rbase to abort
and generate error, I like to insert a code to detect printer driver
if any and proceed or display appropriate "screen message".
Will this be effective approach or is there any better solution?
I'm using RB65++ win. vers
Thankx for any comments.
