Hi,

I need to print some reports from a M128 app in a nice graphical style layout. Any pointers on where to start?

Send the data to your computer and let it print it out?

Thanks for the feedback. I know of several portable devices that simply have a parallel port off the application housing and a simple button to press on the keypad that downloads data to the HP and a really nice preformatted graphical printout is made.

Very simple user interface not requiring a PC go-between. I wasn't sure if anyone on this forum has done this type of thing before. Seems that once the data packet is understood, it could be stored in eeprom, and the application data could simply be plugged into variables before offloading to the printer.

like this...

I am not sure if this helps whatsoever..
but most stores (bestbuy, officedepot,etc) have little "test pods" that hookup via usb and prints a nice picture/word... maybe you can find one of these off ebay.. and dissect it(?)

Just a thought ..

Thanks, I did some more digging and prior posts and the codevision email threads helped a lot. This is what I was looking for...

I plan on using a pre-printed page, with all the fancy stuff already on it. Using a laserjet, and these escape sequences..

The parallel port of a PC printer uses the "Centronics" interface electronics and protocol.
