Hi Derek
You can use VFP report for printing barcode. VFP9 will give you more control on preview. Just you need to select the barcode font in the report designer.

>Hi,
Now I have a bar code library which need calling the GDI (Startpage, Enddoc, etc..)to print out, but I need to print with my dbf file's invoice data.
If use the ? command to print the invoice data and then call GDI to print the bar code,
I cannot control the form feed, because it is two seperate print jobs.
If I not use the ? command, any solution that how to print the invoice data by calling the GDI function ?
