Strange things print in

Some systems require a WIDTH

graphics mode

statement. See your system

 

documentation.

 

Many computers have problems sending

 

one or more of the codes between 0 and

 

13. Avoid any that affect your system if

 

possible.

 

Seven-bit computers cannot use the

 

eighth pin (128). If you have a 7-bit

 

computer and any of your graphics data

 

numbers are larger than 127, change the

 

design so that all numbers are less than

 

128.

 

Be sure that no other commands or

 

carriage returns come between the

 

graphics command and its data.

 

 

Printer freezes in graphics

The printer expects a certain number of

mode

pin patterns, determined by n1 and n2. It

 

does not print until the quota is full. Note

 

that 9-pin graphics mode requires two

 

bytes for each column of graphics.
