I know this would be a kludge of a fix, but what about chopping a long image into printable chunks, NOT cutting the paper, then using the up/down arrows to move the paper back into the printer just the right amount so that the next chunk starts printing where the previous one left off? It would take a bit of trial and error to find the right spot, (assuming that the up/down arrows allow small enough movements that are repeatable), but once you have it figured out, it should work each time.
My original thought was to see if there was some way to send a command to the printer to move the paper backwards a set amount to match what it advances, like the old ESC commands back in the DOS days. If that were possible, then after printing the first chunk, you would issue the command and then print the next chunk.
Not my cup of tea.
However Matt Nolan writes the following on the Qimage list and that is promising:
>>>Success! Using the Z3100 HPGL2 driver I was able to print out a
3'x17' panorama using Qimage and it looks great. The driver offers a
maximum of 91 meters -- I didnt test it, but I suspect it may be
The next thing I want to test is Mike's suggestion of cutting up
gigapixel images in photoshop and then reassembling them in Qimage as
separate images printed on the same page. This is different than the
banner trick where Qimage cuts the image and tries to avoid the page
break (which doesnt work with the Z3100). So if this new technique
works, I dont see that there is anything standing in the way of
printing a 10,000 x 100,000 gigapixel image, or even larger, using
