K225 Frequently Asked Questions

  • When trying to install the drivers for the labeler, setup stops and asks for the Windows installation disk?
  • The manuals for the labeler and the software were not included in the box with the printer?
  • I noticed that there is both a driver and software upgrade available for the K225 Online Labler, but there are two options for downloads FTP and HTTP, which one should I use?
  • The text on the labels being printer is not clear, what can I do to remedy this?
  • The cable that was included with the K225 Online Labler has two connections at one end, which one do I connect to my computer, or do I use both?
  • The installation of the upgrade driver and label software into my Windows NT workstation seemed to go correctly, but when I try to print, I get the following error message "cannot print to specified device the parameters"?
  • When using K225 Online Labler on a Windows NT workstation it seems to default to an address label size although I picked a different label size?
  • When using the clear address labels, the printer does not stop the label to the correct spot to tear it off and the red light starts flashing, what does this mean?
When trying to install the drivers for the labeler, setup stops and asks for the Windows installation disk?

A common problem loading the K225 Online Labler drivers into Windows is that the setup program can not find the three common Windows files (ICONLIB.DLL, UNIDRV.DLL, and UNIDRV.HLP). If this happens, setup will ask for you to place your Windows CD into the CD-ROM where it can find and install the files its needs to complete the setup.

Another option is to browse your C:drive, find c:\windows\options\cabs (if you placed the cabs in this location) and have setup load the files from this location. Once this is done, setup will be completed.

NOTE: The same scenario can occur in either Windows 95 or Windows 98.

The manuals for the labeler and the software were not included in the box with the printer?

Please note that the manuals for both are in PDF format on the installation CD that came with your labeler. Simply browse the installation CD and you will find a folder called MANUALS, here you will find users manuals for the Kroy Label Designer Software and your Kroy Labeler.

I noticed that there is both a driver and software upgrade available for the K225 Online Labler, but there are two options for downloads FTP and HTTP, which one should I use?

By using FTP, you can run the installation of files from our website without having to download them first to a folder on your computer

Use HTTP to transfer the files into a download folder on your computer for installation at a later time.

The text on the labels being printer is not clear, what can I do to remedy this?

In your printer folder right click on the icon for the K225 Online Labler, then click on the properties and go to the control tab. On the control tab you will find the density setting you can increase or decrease the density as needed to compensate for faint or blurry looking text.

NOTE: This situation may also be a result of a dirty print head. We recommend that the printhead be cleaned regularly with the recommended Kroy thermal printhead cleaning kit available on line at be clicking here.

The cable that was included with the K225 Online Labler has two connections at one end, which one do I connect to my computer, or do I use both?

These connections are both SERIAL connections although the larger one looks similar to a PARALLEL connector, they are both SERIAL connectors. Connect to the available SERIAL port with whichever cable ends fits appropriately.

The installation of the upgrade driver and label software into my Windows NT workstation seemed to go correctly, but when I try to print, I get the following error message "cannot print to specified device the parameters"?

You need to edit out of the registry the old Kroy files before adding the new files. Remember to reboot your computer after editing the old files and installing the new files.

NOTE: It is also required that you reboot after upgrading the drivers and software when using Windows 95/98 registry and then install the new files if you encounter this error message.

When using K225 Online Labler on a Windows NT workstation it seems to default to an address label size although I picked a different label size?

Insure that you are using the latest drivers and software for your printer.

When using the clear address labels, the printer does not stop the label to the correct spot to tear it off and the red light starts flashing, what does this mean?

We recommend that you use the white labels in the K225 Online Labler. Also, refer to the manual about the use of the divider that comes with the printer. You need to install it in order to keep the labels from sliding away from the gap sensor inside the printer.

No, the 240SE Series only allows you to print one or the other. However, if this is a feature you need, the K2500 can do this.

How do you clean a machine?

You clean the print head with rubbing alcohol and a Q-tip. To locate the print head, take out your tape cartridge and turn the locking knob as if the cartridge were in. As you turn the locking knob, you will see the print head move. You clean the side of the print head that is closest to the silver pin.

How do you use density?

Density can be used to improve your quality of print. In order to increase the density, press ALT F3. Use the right and left arrows to increase or decrease density. (Older versions of the 240 Series may have a control dial on the left of the machine. If this is the case, turn the dial toward the "+" sign to increase density and toward the "-" sign to decrease density.

How do you print vertically?

Make sure that SIZE (F3) is set to BOTH, SIZE 1. If you try to print vertically with SIZE 2 you may get a text too tall prompt. Press STYLE (F4) until vertical is displayed. Press "Y" for yes and hit space or enter. Type text and print. Additional vertical font cards are available in 16, 24 and 30 pt.

What is "set line length" and how do you use it?

This feature is available with the 240SE. Line length sets a specific label length from 0-6 inches. It can be used to set a specific label length or to justify a single line label.

In order to set label length: press ALT SHIFT F3 and set line length from 0-6 inches. You must enter 2 digits for each line length. For example, if you want to set line length at 6 inches you would enter "60".

*This is only available machines with version 6.03 or better

How do you justify?

This feature is available with the 240 SE. In order to justify your label: select the number of lines you need for the label (ALT F4). Press ALT F1 and scroll (using the right and left arrows) to Left, Right or Center. Choose one, press enter. (This will justify all lines on your label).

If you are justifying a single line label on a 240SE. Set line length (ALT SHIFT F3) from 0-6 inches. You must enter 2 digits for each line length. For example, if you want to set line length at 6" you would enter "60". Press ALT F1 and scroll (using the right and left arrows) to Left, Right, or Center.

How do you print multi-line labels?

This feature is available with the 240SE. To print multi-line labels: press ALT F4 until the number of lines you want to print are displayed, press space or enter. Type your text (press enter to go to the next line in your label) and print.

How do you use the accent symbols?

The accent symbols are located underneath the A, S, D, F, and G keys (the symbols are blue). Accent symbols can be put over vowels only. In order to select an accent symbol: press ALT and the accent symbol that you want. Release the ALT key and type in the vowel that you want the accent over.

For example, if you want to put a tilde ~ over an "E": press ALT "A" (because the tilde is located beneath the "A" on the keyboard), then type the vowel that you want the accent over, in this case "e".

How do you do sequencing?

In order to sequence: press ALT F5. Choose either A (for Alpha) or N (for Numeric). (You can't choose both). At "Start char" enter the number or letter you want the sequence to begin with. At "End char" enter the number or letter you want the sequence to end with. At "Incr #" enter the increment number you want to sequence by. An omega symbol should appear in the text box. Press "print" to print the sequence.

K2500 Frequently Asked Questions

  • Can you print bar coding and text on the same label?
  • How do you use file management?
  • What is the paging feature and how do you use it?
  • How do you sequence?
  • How do you justify text?
  • How do you change the point size?
  • I keep getting the "Text Too Tall" prompt.

  • How do you hook the K2000 up to a PC?
  • How do I use wire wraps with the K2500?
  • How do I save files in the K2500?
Can you print bar coding and text on the same label?

Yes, the K2000 series has this ability. In order to do this: go into F4 (Bar code) and scroll (using the arrows) to the bar code that you want to use. Press enter. Go back to your text screen and type your bar code information. Press enter. You should be on the second line now. Go back into F4 (Bar code). Select "None", enter. You should be back to the text screen. Type in your text.

If you get a "Text too tall" prompt, make sure the point size is not too large. If you need to make the point size smaller: press F2, SIZE, enter a smaller point size. (Make sure your cursor is at the beginning of your text before changing the point size).

How do you use file management?

Press F1 for the file management function. You have 4 menu options: New, Open, Save and Delete. NEW will start a new file. OPEN will open a saved file. SAVE will save a format or text as a file. DELETE will delete a saved file.

What is the paging feature and how do you use it?

The paging feature allows you to enter more than one label at a time. For example, if you have to make three different labels, instead of making one label and pressing print, making the next label and pressing print, and making the final label and pressing print, you can enter the information for all three labels at once and press print once.

Enter the text for the first label that you want to make. Press shift and the down arrow. This creates a new page (or label). You can now enter the text for your next label. When you have finished making all of your labels, press print. All of the pages (or labels) will print.

How do you sequence?

In order to sequence: Press F3 and then "S" (for sequence). You should get a menu of INSERT, ALPHA, and NUMERIC. INSERT allows you to add the sequence feature to a file (if you want to insert a sequence into a saved file, the file must be opened first). ALPHA allows you to sequence using the alphabet. NUMERIC allows you to sequence using numbers. After you have chosen INSERT, ALPHA, or NUMERIC you will get a prompt for the start number or letter, followed by a prompt for the end number or letter, and finally a prompt for the increment #. After you have entered this information, an omega symbol will appear on the text screen. Press print to print the sequence.

How do you justify text?

In order to justify: press F2. Press "J" for justify. Choose Left, Right, or Center. (If you are justifying already typed text, make sure that the cursor is at the beginning of the text that you want to justify).

How do you change the point size?

In order to change the point size: press F2 followed by "S" for size. Enter the point size you want and press enter. Press Esc. Type in text. (If the text is already typed in make sure that the cursor is at the beginning of the text)

I keep getting the "Text Too Tall" prompt.

There are a few reasons that you could be getting this prompt. You will get the "text too tall" prompt if the point size you are trying to print is too large. For example, printing 4 lines at 36 pt. would be too large to print on a one-inch label. You would need to make the point size smaller.

You will also get the "text too tall" prompt if you use the delete/backspace key to create a new label. (i.e.: Instead of using F1-NEW, you simply delete the contents of your current label and type your new label). When you do this, the attributes pile up at the first character and confuse the system. If your system is already confused, you have to reboot it. This will erase ALL of your files and clear the system so the "Text Too Tall" prompt doesn't come up. In order to reboot the system, turn the system off. When you turn it on, hold down the ESC key. If you want to avoid this problem, you should always make a new file for each new label you create (F1-New).

Can the K2000 work with Windows?

Yes, Kroy has a Windows driver available. This will allow you to use Windows 3.x or Windows 95 with your K2000. Windows driver support requires K2000 firmware rev 3.3.x or greater, or K2500 firmware rev 4.1.x or greater.

How do you determine the firmware revision level?

Hold down the SHIFT and ALT keys and press the V key.

How do you hook the K2000 up to a PC?
