For those who print custom sized documents using Inkscape, I ran across another app which seems to work very well printing BOTH banners AND posters.
Check out Posteriza 1.1.1 (www.posteriza.com).
So far this app has printing everything I've drawn (if thats what you can call my attempts to draw). I can enlarge to HUGE sizes.
Save your Inkscape document as either a bmp or png file (the two I've tried to date). Open in Posteriza, make the size changes, and print away (and yes, HPs can print banners - I've finally had success with mine - I say this for my benefit. I was ready to throw the printer out the window).
I sincerely hope that others can use this information. I've received so much support as I attempt to print odd sized things, I want to repay in any way that I can. Inkscape is very cool and fits absolutly perfectly in my class where students just love it. Now that I can print their work with no porblems (so far), the kids are almost too excited.
Again, thank you everyone!!!
