>>>The problem is:

>>>VFP 5.0a
>>>Win 98
>>>Printing to the HP6P Enhanced or later HP Printer driver (regardless of specific printer - the 6p enhanced was the first where the problem showed up.)

>>>Usually the 98 machine is mapped to the printer through Novell File & Print shareing Service - as opposed to the Microsoft service. This seems to agrivate the situation, but is not required for it to happen.

>>>Problem:
>>>Once the system has printed, it will get an Exception error. The simplest reproducable example was a program that did this:

>>>type c:\autoexec.bat to print
>>>select * from tablea, tableb where tablea.field = tableb.field

>>>Where the mapping field was an integer, and one of the tables had stars (****) in the field.

>>>Note: The problem often occured on other commands in different parts of the system, such as setting an Enabled=.T., a DODEFAUL() - didn't really matter. Once VFP printed to that printer, the damage was done, and it would soon crash.

You might try the latest drivers. However, I found that PCL 6 has problems. We have an HP 4000 and are using the PCL 5 driver.
