Hi Al,

Try to create new printer form using my How to add/delete custom printer forms under Windows NT/2K/XP FAQ #21202. Internaly form size is stored in 1/1000 mm, so you can get better precision this way.

>I'm printing to a custom form 7" long using an Okidata ML520 printer in IBM mode. These are continuous, tractor-fed forms. I've set up a custom form length in the print server for this printer. When I print the report, everything works fine except the form length is very slightly off. If the form length is set to 7.00 inches it seems to print about 7.006 inches, so the print goes slightly lower each form until it's completely out of whack. If I set the form length to 6.99 inches, the printing goes slightly higher each form until it's out of whack again. For some reason this printer refuses to print a form exactly 7.00 inches long (measured).

>I tried switching to metric measurements for finer control (0.01cm vs. 0.01") but that didn't work. Form length of 17.78 cm is too long, 17.77 cm is too short.
