A line is usually 1/8" high. So you essentially have a matrix running at "n" characters per inch horizontally, and "m" fractions of an inch vertically. Fit your print into this matrix - some people do it with an array, others just work the spaces. Provide a "test" ticket so the operator can get the printer lined up. With a tractor feed, after that you are good for a whole box of tickets. Oh - one more thing - you may have to advance a number of lines so the ticket can be torn off after printing, then reverse feed the same number. Another tip - set your page length just to the height of the ticket. You really want to exploit the basic native font built into the printer. Hope this helps - Miles
