I have a VFP9 app that has developed a new and intermittent printing
error problem.
When printing a report, I randomly get a
"Detail 1 band is too large to fit on page"
error when running one particular report. Thinking it was just a problem
with the report spreading out into the left/right margins as the error
suggests, I reworked the report and now have 3/4" blank space on each
side, using nothing but Arial typeface. No change in the problem, the
error keeps coming up randomly. When the error happens, there is no
output, no paper, nothing sent to the printer.
This application and report just recently developed this problem and it
happens on different computers...all running Win 7 or WinXP.
I have changed printer drivers from Postscript to XL. Still random
errors. I installed the printer drivers from Microsoft's auto-download
and install routine in the printer setup. NO change. Downloaded and
installed the printer drivers from the manufacturer (Lexmark)...no
change. I have also checked and cleared the "printer residue" settings
in the FRX file memo fields before compiling the application to an EXE
(the report file is included.)
Finally, one "fix" that always seems to work is to close the application
and reopen it, and the report prints fine. Every time.
Obviously there is something being changed by something as the
application is being used for various tasks...some setting or value is
being left in a state that causes this printing error to happen, even
though the report is good, the data is the same, and the printer(s) are
okay. The "other" tasks that this application does are pretty standard:
obtain and store data from DBF and MySQL files, display forms on screen,
etc. Nothing fancy or edgy. Also, this gremlin has been giving me grief
now for over a month, and it is consistently random. 20+ computers use
this application every day and there will be 4 or 5 error reports each
day from different systems at different locations.
Question: Where would you look or suspect as being the cause of the problem?
Thanks for any WAGs or war stories!
