7.6.2HELPFUL HINTS

1.All x,y values (start, end, center, increment) are measured in n/300 of an inch. The origin of the x,y-coordinate system is the top left-hand corner of the printable area of the page (see Figure 7-8).

The printable area of the page may vary with the printer model and paper size being used. Refer to your printer’s user’s guide for specific information.

2.The complete command string must be entered as shown below. Incomplete command strings and command strings with invalid values (such as spaces) will cause the Card to print the string at the place where the error occurred.

For example, suppose you enter a line-command string with an invalid <x start> value:

¬GL30;A;1;1;600

The Card would cause all characters, including the invalid value “A,” to be printed:

A;1;1;600

3.As an alternative to using the semicolon “;” as a separator between parameters, you may also enter a comma “,” or a forward slash “/”.

4.Do not enter numeric values with commas (for example, “50,000”).
