Hi,

I wrote a simple label programme for my own use. It prints a carton list
to a Xerox laser printer (network) on A4 paper and small sticky labels
from a Dymo 400 printer (local USB).

The problem is that if I print the A4 list first the labels printed on
the Dymo are messed up - prints a label and then feeds 2 or 3 labels
before printing the next label. Also, if I print the labels then the
list the list prints on the wrong paper (US Letter) and wrong
orientation (landscape).

If I quit after printing either the labels or the list and launch the
app again and print the other it works fine.

I really don't want to select the printer each time so I've hard wired
both printers to two different "print" buttons.

Code follows for each button. Any help appreciated, thanks.

Regards,

Paul
