right to left

[INPUT] -> [PRINT]
[9] -> [nothing]
[0] -> [nothing]
[f] -> [nothing]
[sin] -> [90.00] SPACE SPACE [SIN] CR LF [1.00] SPACE SPACE [***] CR LF
[g] -> [nothing]
[sin-1] -> [SIN-1] CR LF [90.00] SPACE SPACE [***] CR LF
[987654321.9] -> [nothing]
[PRX] -> [987654321.9] SPACE SPACE SPACE SPACE SPACE CR LF
[STO] -> [nothing]
[0] -> [STO0] CR LF

nop, look below

there is alway a CR LF at the end of the operation so the print head is ready to print whatever it need to print

paper result (picture)

Code:

      90.00  SIN
       1.00  ***
            SIN-1  // -1 is superscript and takes only one character space
      90.00  ***
987654321.9     
            STO0
                   // right aligned print head is ready to print

note: all printing is done right to left so what the print head does for the following line
[987654321.9] [PRX] -> SPACE SPACE SPACE SPACE SPACE 9 . 1 2 3 4 5 6 7 8 9 CR LF

edit: typo + add picture + note
