#ALLEN BRADLEY LABEL PRINTER PRO SERIAL#
And I come from a serial *nix background. But, I decided that investing in the serial printer market was not a strong You grabbed my interest because I have thought to make such an item just for PLC applications and others where for whatever reason it's not practical to output format strings. I know there were printers for the cash register / label / ticket trade that would store aįormat so you just sent the numbers, but the pointy clicky crowd obsoleted those years ago. The easiest solution would be to use a PC to accept tokens and put out the strings with all the formatting. But, with the trend being toward less or no intelligence built into printers (Winprinters), and 232 serial being drummed out, I think you are looking for something either highly specialized or non-existant. This is what many people use a "BASIC" module for, although that is a horribly expensive way to go even if you know the gizmo and can program it quickly. any other approach is likely to drive you insane. the best thing to do is make sure that you can use the PLC’s DH+ port for future programming and reserve the serial port for the printer’s use.
so if you’re currently using that port for programming purposes, you’re going to run into a lot of aggravation down the road. Keep in mind that this is probably going to tie up your PLC’s serial port. the printer should be able to print the string. the “serial-to-parallel” converter should take the serial output and make it compatible for the parallel printer. then send the string out through the PLC’s serial port using the proper ASCII command. The basic idea is to have the PLC take the value (quantity in yards) and convert the integer into a string value. so what brand and model are you working with?Īnyway, I used a “serial-to-parallel” converter (from Black Box if I remember correctly) between the PLC’s serial port and a readily-available parallel printer. I did something like this several years ago with an Allen-Bradley PLC-5 (enhanced) processor.
