APPENDIX A- FREQUENTLY ASKED QUESTIONS

These FAQ’s are in no particular order. They cover the most commonly encountered questions asked

about our mobile printers.

Q. The rst label I print is ne, but the next one starts printing not as close to the top of the label form,

then sometimes skips a label, then prints a good label.

A. Make sure that you only have one carriage return/line feed pair after the PRINT statement in your

label. If there is more than one CR/LF pair, the printer prints the label, then sees the extra CR/LF

pairs as data to be printed in line print mode. This advance causes the next label to be registered

incorrectly when a new label file is sent.

Q. I send a label to the printer, and the label begins to print. Before all of the label is printed, there is a

feed to the next label. This happens for 2 attempts before the printer stops.

A. Make sure that the label length specified in your command line is shorter than the distance between

your eye sense marks on the label stock. If you are asking to print, say a 400 dot long label and the

label stock eye sense marks are 300 dots apart, the printer ‘sees’ an eye sense mark before the entire

label has printed and assumes the label stock was not at top of form. It then feeds to the next top of

form and tries again. After 2 tries, the printer advances to the next top of form and stops.

Q. When I send a label to the printer, the label le gets printed, and not the label itself.

A. If you are getting the label file printed instead of the label, the syntax of the first line may be incorrect.

Check that the syntax is something like: ! 0 200 200 210 1 where the 210 is the label length and 1 is

the quantity. If the printer detects an invalid first line, the command mode is not entered. Instead, the

printer acts as a generic line printer, and the remaining lines are treated as raw text to be printed.

Q. My printer doesn’t seem to respond when I send anything to it.

A. Make sure that you have the same communications parameters for both the printer and the device

connected to it. You can determine the printer’s settings by turning the printer off, then while holding

the feed key down, turning the printer back on. It should respond by printing a report, pause for about

3 seconds, then print a second report. If you look through these reports, you will find an entry for the

current baud rate setting.

A good progression for finding problems like this is to use the MPU.EXE utility. Connect the cable,

then turn the printer off. Now run the MPU utility. When this utility starts, it should turn the printer on.
