I am currently developing an app. I am working on a report that prints
an invoice. It printed fine yesterday. Today when I click the print
button to preview the invoice and then click the print button I get this
error message:  Printer selected not valid.  What changed from
yesterday??  What does this error mean and how do I fix it? Thanks.

Did u check up the printer setup
regards/angshu

I preview the report when the user clicks the button.  If I go into printer
setup on the menu of the preview screen, the printer is set to the printer I
am trying to print to.  When I click the print button on the preview screen I
get the error message.  Clicking on either the printer setup or print buttons
again does nothing.  I don't know what happened to this form to give me this
error. I have other reports I print from this same form ( by clicking a
different button of course) that still print properly to the same printer I
am trying to print this report to.  This is driving me crazy!  Thanks for any
help anyone can offer.
