Radio Shack TRS-80 PC-3 Owner's Manual page 148

With the second form of the LPRINT statement, the paper is divided into two 12-character halves and the two values are printed
in each half according to the same rules as above.
With the third form, the print always starts at the left edge, and each value is printed immediately following the previous value
from left to right with no intervening space.
It is possible to cause PRINT statements to work as LPRINT statements. See the PRINT verb for details.
If an LPR INT statement contains more than 24 characters, the first 24 are printed on one line, the next 24 on the next line, and
so forth.
Unlike PRINT, there is no halt or wait after execution of an LPRINT statement as there is with PRINT.
