Chapter3 Handling Recommended Module Values Print directions of a barcode are as shown below. The recommended module values vary by paper type, barcode type, and the print direction. Paper width direction Paper width direction Paper feed direction Paper feed direction Fence barcode Ladder barcode If [Rotation Settings] is set to [Normal] or [Rotate 270 Degrees], the barcode will not be printed. CAUTION For ANSI Grade C or higher (minimum module size is 600 dpi) U Page 111 For ANSI Grade B or higher (minimum module size is 600 dpi) U Page 112 • Readability of a barcode varies by paper type, performance of a barcode reader, or other factors.
Furthermore, drop in print quality due to clogging of print head nozzles or skew of ink drops can cause a barcode to become unreadable. In case it happens, it is recommended to print HRI characters or take other measures. • Due to characteristic of ink, ink seeped into paper may cause the bars of a barcode to be printed thicker. In such cases, carry out [Bar Width Adjustment] that reduces the bar width by 2 pixels, and increases space width by 2 pixels. • If the printer is subjected to vibration or shock during transportation or installation, the barcode rank that can be printed may decrease. In this case, [Adjust Uneven Colors] may improve the barcode rank.
