A client has a situation where they want to print two different preprinted
forms and collate the result, something like:
Tray 1: blue copy of paycheck
Tray 2: canary statement of earnings
The well-known VFP trick is to establish two different reports and in
Windows create two different named printer profiles and then alternate:
DO WHILE NOT DONE
REPORT FORM Paycheck TO PRINT PRINTER 'BlueTray' NEXT 1
SKIP -1
REPORT FORM Statement TO PRINT PRINTER 'CanaryTray' NEXT 1
ENDDO
or similar pseudo-code. Works great, right up to the point that it don't.
This appears to be a classic case of a race condition.
Use something other than print queues. Print directly to the
printer, or have two printers.
