AP Check MICR Line Adjustment

I have an RTF check template for AP checks that I created and it is working really well.  It took me awhile to get the MICR line in just the right position but I did. (Yeah!!)

We would like to change the printer used to print the checks but in my testing, i need to move the MICR line down about 1/8th of an inch (using the same HP Universal Printer Driver) so the characters will be in the location and position necessary to pass MICR reading.  It seems that I have reached the bottom limit of the margin and any little tweak I do causes the MICR line to flow to page 2 (we are using a template that only has one page).
