Well, Ryan, the little box on my PC says "HP Photosmart 7150 series". Mine is probably a low end model as it lacks the slot for a digital camera memory card and an LCD preview screen. It takes a 57 color cartridge and a 56 or 58 black. It's USB connected. It'll do 4800x1200 dpi. I'm amazed at the quality of detail of even the smallest text I've done. That would be some of the warning data like "Fuel Cut Off" or "Danger 600 Volts" etc. Every letter has crisp, clear serifs even though I need a magnifier to see them! Maybe not Microscale quality but certainly adequate for the non-contest modeler, especially under a coat of weathering. The ink appears to be oil-based as it takes a while to dry and has that "texture" to it. I ran a 20 year old sheet of decal paper through it with no problems.
The other aspect of this decal thing is the source file and application. I set up a 1200 dpi document using Photoshop to print from. Any good image editor will work as you can adjust the resolution of the file. I don't know if a word proccessor will do that. A 1200 dpi image creates a huge file that takes some time to print and modify, but the results are worth it. It won't do as well from lower rez files. Until I started using high rez documents to begin with, my print-outs were Joe Average, even with the photo printer.
Of course, you can't print white, though you can knock white out of another color with a paint program and print on white paper . And the light colors are not opaque enough to cover dark paint on a model. But for dark or black letters and graphics the potential is high. This weekend, I hope to actually use some of my test shots as decals after clear coating them. I hope it works! The PC has great potential especially for free-lancers. I've hated lining up dozens of teeny little letters on the hood of a diesel!
Good Luck,
smyers
