What did the vertical tab use to look like?
- tyingq 5y agoHere's a good example in this printer manual: https://mpi.com.es/wp-content/uploads/2015/06/USER-GUIDE-IGP-DASCOM-TALLY-T2265_T2280_EN.pdf https://mpi.com.es/wp-content/uploads/2015/06/USER-GUIDE-IGP... Search for both "vertical tab" and "VFU" (Vertical Format Unit). The "VFU" would accept commands to set the vertical tab stops to match whatever form you had. Say there was an address box that was 6 lines the top, a multi-line field 10 lines from the top, and an SSN field 15 lines from the top, and so on. You could program those tab stops and have a tractor feed of those forms loaded. Which would be easier programmatically than, for example, doing the math on how the length of text in some multi-line field in between those two would change the amount of line feeds you would need to send to land in the SSN field. So, something like: <vt> Enter the Address Stuff <vt> Enter some amount of multiline text without having to calculate how many lines it filled <vt> Now you're in the SSN field
