PRINT command for phototypesetter in 80s
When phototypesetters were already old in the late 80s, i used a TOSHIBA T1000 to feed text that came on 3.5 floppies into the parallel port of an AM typesetter. A nice serviceperson had given us the schematics of the punched tape interface, that was converted. Only the TOSHIBA laptop was slow enough not to overrun the typesetter. Then i found out that the DOS PRINT command used the IRQ line. Now we could use a more modern (faster) DOS machine to feed the raw texts into the typesetter. I remember that the PRINT command was a rare multitasking program under DOS.
