Re: HP48 Printing in Trace Mode Message #2 Posted by Thomas Chrapkiewicz on 15 Dec 2007, 2:10 p.m., in response to message #1 by Gerry Schultz
The HP48 series has a different sort of 'Printer Operating Paradigm' that the 67 and 41 Series.
The 48 provides a number of Printer functions (PR1, PRST, PRSTC, etc...) that you embed in your program. When your program executes and these printer functions are executed, the appropriate values are sent to the printer. The printer that they are sent to is dependent on how you have the IOPAR (IR/Wire, etc) set. Thus, the printer can be either a 82240A/B or serial printer(or other serial device) near or attached to the 48. If you have the IOPAR set to communicate with an 82240 and the printer is not on or close to the HP48, the program will continue as the IR communication with the printer is one-way. This of course will impact program execution time. This time can be adjusted via the DELAY parameter in the IOPAR. Of course, you could create your own type of TRACE mode by modifying your code such that Printer related command execution is dependent on flag setting(s).
On a related note, I have used a 'Home IR repeater' (devices designed to send Home Stereo/TV remote commands via RF throughout the home) to send HP48 IR printer output across my home.
Hope this information helps,
