Problems with printer output
When you use transparent printing you may obtain incorrect printer output due to the
following reasons;
Graphics printers may misinterpret some characters output through transparent print. This
problem is more likely if the terminal is in 7-bit mode, because 8-bit characters will not be
printed.
Some terminals suppress the output of certain characters to their printer or AUX ports. Such
terminals can prevent essential control characters from reaching the printer thus generating
incorrect printer output. This occurrence is extremely unpredictable because of the large
number of potential hardware configurations.
