>From my observations the M100 doesn't do anything special when printing text. It looks like you are attempting to connect a Windows printer to the M100 so the problem may be, "Is the printer expecting something from the M100 that's not being sent".
Hardware handshaking on the Strobe, ACK, and Busy signals vary by computer and printer manufacturer and model. Okidata and Epson dot matrix printers used to have dip switches to accomodate the various polarities and timings of these signals used by different computers. Its possible what your printer is expecting doesn't match what the M100 is expecting. If that's the problem you may not be able to connect the M100 and Canon printer together as most inkjet/bubblejet printers no longer have these settings. Most Windows printers expect elaborate setup strings from the print driver even when printing unformatted text. The M100 won't be sending any of that so results will likely be unexpected. I would suggest consulting the technical manual for the printer, if there is one, to determine what hardware handshaking is required and what setup strings needs to be sent to the printer before you can send ASCII text and control codes for printing. Depending on the printer and the M100 application, it may or may not be possible to print text from the M100 on the Canon printer.
