Host print jobs that contain Printer Control Language (PCL) codes are not formatted correctly because PCL codes similar to the following are printed instead of being processed by the printer: 
&l0O (8U (s0p10.00h12.0v0s1b3T &k0G

↑ Back to the top

Cause

This problem occurs because the embedded PCL codes under 0x40 that are present in LU1 print jobs are converted to spaces. For example, EBCDIC 0x27 (an Escape character) is converted to ASCII 0x20.
