So it seems that SI-Print (version 2.0.2) doesn’t work anymore – at least not in Windows 10 with the printer control directly connected. I could not talk to it successfully when directly
connected to the computer with a USB-to-Serial cable and then through a null-modem (the grey cable with a female 9-pin socket at either end).
SI-Print just wouldn’t work. SI-Config+ talked to it just fine, and a terminal emulator showed me that the printer control sent the correct data.
But there is a solution. SI-Print does work when a download control is connected, and the printer control is accessed as Remote. You can’t use SI-Print to test y
our layout, but you can leave your printer connected to the printer control and test on the printer itself.
Below are the settings I specified (follow your printer specifications, and type a percent - % to code the ESC character), and the finished goods, below.
The printer specific codes for the current SPORTident printer (MCP7830 by Martel) can be downloaded at http://martelinstruments.com/sites/default/files/images/stories/datasheets/mcp7830_adq.pdf
Make sure to use the tables on page 5 (RS232 mode).
