Some of our clients have Line of Business Applications that go way back. This is especially true for accounting firms where folks will come to them to fill out tax reports for years gone by.
Some of those LoBs were DOS with no other option to run them.
So, we get the app set up in XP Mode on the Windows 7 system, from there we need to run the following command in the command line shell:
- net use lpt1 \\pserver\laser1 /persistent:yes
Since 99.9% of our clients don’t even have a parallel port on their computer anymore, it is probably quite safe to use LPT1. For those rare cases use LPT2.
One can either point that command to a server share or share the locally attached USB printer making sure that the firewall allows the connection.
Note that in our experience both HP and Lexmark printers seem to work okay for this process. The actual printout may not be what is expected, but it works. If using any other printer vendor’s products this may or may not work due to driver or PCL language issues.
