Yeah such problems happens when com port versions are mismatched with OS supporting drivers.

So in that case, you should repair you OS or restore it to FACTORY settings.

By doing this you will be able to regain your all configuration for all ports available.
I hope this will work out for your problem.

Tried different ports, different usb cables. No luck. It shows in the devices but will not print

Check for the printer requirement for operating system and maybe it is not compatible.

Correct Printer icon name. Correct usb port driver needed. Check your device manager for usb port driver if properly installed. otherwise use LPT port if there is install driver for your computer.

How to find the com port for the USB driver

You have to look in the device manager. Usually you can get there by right clicking on My Computer then selecting Properties then the Hardware tab and Device Manager. If the CS1504 pulled a virtual COM port it will be listed under Ports (COM & LPT) as Prolific USB to Serial Comm Port with the port named at the end of the line.

My older hi-pro box will not work with my serial to USB adapter. It keeps saying it cannot find it on com 1,2,3,4. In the device settings it says the hipro is on port 2 and the serial/USB bridge is on port...

I just set up a serial Hi-Pro box for one of my customers on their new laptop. According to Beltone, the only usb adapter that will work with the Hi-Pro (or at least the only one they have gotten to work) is a Belkin F5U409. I know some usb serial adapters don't use true serial communications if that makes any sense, so there isn't really a baud rate. They kind of just send out the communication in bursts...

In any case, ive only tried with the belkin adapter and that worked fine with no problems. The other point here is that your Hi-Pro and Adapter are on different com ports... This is odd, the hi-pro should be on the serial adpater's com port. Also the software i was using - Noah, with a beltone module for programming hearing aids.. only looked on com ports 1-3. The computer put the serial adapter on com 8 - which would not do. I checked for available com ports and saw that 2 was unused. I set the adapter to 2 and was able to set up the program normally.

I did this on Windows 7 Professional 32 Bit. The procedure for selecting the com port is the same on earlier versions of windows.

First, open device manager, open the list titled "Ports (COM and LPT)". You should see your serial adapter in there. Double click it. In the window that opens click the "ports" tab, and hit the button labeled "Advanced" In the window that opens there will be a drop down list to select a com port. Select the desired com port and hit ok. That should fix it.
