I use The GIMP to copy and scale sections of NOAA products to make my on charts of harbors and rivers, complete with a transplanted compass rose and position rulers along the edges.
If you are printing with an ink jet, water soluble ink is a problem unless you are using certain picture printers. Color lasers do not, and are quite affordable these days if you are happy with 8.5" x 11" or 8.5" x 14" but 11" x 19". The start around $500.00 and have much lower printing costs per page so you recoup the extra cost over the lifetime of the printer. I use a Brother 9460CDN laser printer to print my charts either on letter or legal sized paper.
Sadly, larger format laser printers are still out of reach. When they drop below a boat buck I'm going to get one!
