I don't really know the technical details of device drivers, but I thought they were not port type specific, so I thought that it might be possible to hook the printers up via usb and have Windows treat the USB as a serial connection. I was really hoping to be able to make this work without additional hardware.
So the real question: Is there a way to have the workstation (Windows 7) identify the usb connection as a serial com port so that it could pipe the serial port driver output to the printer via usb (masking as serial)? What are the odds that it would work?
I use the cheap chinese CH341 USB-Serial (RS232) cables. With the driver on Windows, I can quite happily use it to configure routers/switches and I also use one on a thermal printer (though controlled by a Linux box)
Not had any issues with them, myself, and they only cost a few quid.
Got the Windows 7 driver. Before installing the driver, the device was recognized as a PRI USB PRINTER and showed up under Devices and Printers, but in the Unspecified section. With installation of the driver, there was no change to that, though I did have to install the printer (which gave a printer icon under Printers and Faxes in addition to the PRI USB Printer icon). The printer does not show up under device manager. Looking at the Printer Properties and the Properties for the PRI USB Printer, showed nothing that looked like COM port settings.
Hmmmm, that might be an artifact from a piece of software that sort of-kind of did usb to serial translation but required writing your own drivers... but it didn't show up until I plugged the printer in via usb, and when I removed it, it reinstalled itself (again with the printer attached via usb).
