8. Aspect
value
[2-byte decimal] 1–1000
Specifies the aspect value.
Actually, this is 0.01–10.0, but since the decimal
point cannot be entered, a value multiplied by 100 is
entered.
The default value is 50. (The actual value is 0.5.)
Note
* Some barcode readers cannot recognize a barcode with the cell size specified as 1 dot or 2 dots.
* If a setting for the symbol size (X direction) or symbol size (Y direction) has been specified
manually, the aspect value setting is ignored.
* If a setting for the symbol size (X direction) or the symbol size (Y direction) has been entered
manually, the bar code may not be printed or an unreadable bar code may be printed.
* If both a large cell size and a high level error correction capacity have been specified, printing
may not be possible due to a full print buffer.
[With symbol type MicroPDF417]
* Since the error correction capacity is automatically determined from the symbol size (X direction)
setting, the settings for “error correction capacity and type” and “error correction capacity-value” are
ignored.
* The aspect value setting is ignored.
* The following table shows the values available for the symbol size (Y direction) according to the
symbol size (X direction) setting. If an invalid setting is specified for the symbol size (Y direction), the
default setting is specified.

(2) Barcode data
The numbers of barcode data characters that can be entered are as follows.
1850 alphanumeric characters, 2710 numbers, 1108 binary bytes
Note
The numbers listed above are for an error correction level at a high-density level (L 7%). If the
standard level or higher is set, the number of characters that can be entered may decrease. In
addition, even if the characters are entered with the high-density level (L) specified, the number of
characters that can be entered may decrease due to compression.
