13.2.6.6 LIOCS Printer File Definition
The methods of processing printer files are the same in VSE and MVS.
Differences exist only in the CNTRL and PRTOV macros.
Differences exist only in the CNTRL and PRTOV macros.
CNTRL Macro
Notes:
1. MVS does not support delayed printer control.
2. The MVS Job Entry Sub-system supports machine and ASCII control
characters.
PRTOV Macro
The PRTOV macro results in the same action in VSE and MVS. However, if you
use CNTRL, you cannot use SYSOUT=A and must specify the printer in the UNIT
parameter of the output data set DD statement. Since this is rarely a viable
option, programs that use the PRTOV macro should be converted to use a line
counter instead.

Figure 34 on page 297 shows a comparison of the DTFPR and DCB operands.
