Serial to USB printer install.

May 13, 2013 at 12:49:45
Specs: Windows 8 64, 2.661 GHz / 6142 MB
I have a zebra S300 printer which has a 25 pin serial port. I have one of these adapters 1.8M USB to RS232 DB9 Serial Male Cable / DB 9 Female to DB25 Parallel Adapter
I have plugged it into the printer and the PC, the pc detects the adapter and installs a driver for it. I then run the drivers for the printer which asks me to choose a Port that the printer is connected to. The problem is I have not Idea what the port is called or how I find it out? I am running windows 8 64, also have a virtual machine running XP Pro 32 just encase its not compatible with 8. Please help.

If windows installs a driver for the adapter then it might show the port for it in device manager.

There's no 'port settings' or 'details' tab there to click on for more info?

When it asks you to choose a port does it give options--LPT1, com1, etc? If so you might have to go through them all and see which one gives a connection to the printer. If none do it might not be possible to connect that way.

Did you get any instructions with the adapter that might help?

no its one i found in a draw full of cables, looking online it seems it is not installing correctly, it should install as a port rather than the way it is at the moment as a HID :/

I'm not sure how to do that.

If it's a desktop PC it might be easier to get an add-on serial or parallel card (whichever you need) and connect it there.

Hi Advarntek,

suggest you tread carefully as you mention both serial and parallel in your posts, and both (generally ) use 25 pin sockets.

They are not compatible and if one is wrongy connected to the other, almost certainly serious damage will occur, most likely to both ends of the connection.

First you need to be sure which connection your printer has.

Good luck - Keep us posted.

It has a RS-232 serial interface which 8 miniature switches above it.

Hi Advarntek,

in which case, under no circumstances use a parallel connection.

Note; the adapter does *NOT* appear to provide a 25 pin serial plug only a 25 pin parallel one, which suggest some conversation is happening from the 9 pin serial.

Serial interfaces have to be configured at both ends, e.g.
speed, 6/8 bit, parity, etc.
This is probably what the switches are for.
At the pc end, under dos, the MODE and COM commands were used.

Is there a possiblity the printer also has a parallel interface behind a cover?
If so, use it - it is a much easier connection.

If possible avoid using usb as this is adding a complexity, which might be contributing to your problem.

Good Luck - Keep us posted.
