just a thought but have you tried installing the same printer again on the
same port, but with a different name?
I sometimes do this and set one to default black and white and the other to
colour ,so all i have to do is change the "printer" instead of settings. But
this could possibly help if it thinks its printing through a different
driver.
the other thing is.. have you tried the printer.enddoc method to close the
printer port before trying to open it in your app?
may or may not work.... but its just a thought

Hi.
I have a computer running a third party software (POS). The thing is
this application opens the printer port and I need to use another
program while the first one is still running.
Since the other app has the printer port windows shows an error
(path/file access error).
Is there a way that two applications can share the printer port?
Thanks for your help.
William.
