STRING 8X8 10 10 HELLO

END

If the printer will not print this label but does print labels that were

prepared on another system, your system may not be compatible

with the printer. The most common cause of this is improper end-of-

line termination.

NOTE: Hex dump mode allows you to see every character that reaches the

printer. Use of hex dump mode can help resolve some programming problems.

11. Check the label format header line.

When a particular label format will not print or is cut off at the

bottom, the trouble is frequently in the header line. Check the

header line before continuing. Especially check that the header line

begins with the proper mode character and specifies the correct

number of dot rows. When programming portable printers, the

header line should be preceded by the wake-up string.

12. "Comment out" portions of the nonworking label format until

your results improve.

You can usually isolate a bad printer command by placing a "C"

before selected command lines. Begin by commenting out the most

complex lines, then try printing the format again. If the problem

persists, try commenting out every line between the header line and

the END statement, then add lines one at a time to see which lines

are at fault.

After you have isolated the portion of the format that does not work,

examine it for errors or test it by itself in a simpler format.

NOTE: When examining label formats, look for instances where the letters "O"

or "I" have been incorrectly entered for the numbers 0 and 1. These are very

common typographical errors.
