What Is the Difference From PCL5 & PCL6 Drivers?

Hewlett-Packard developed the Printer Command Language, or PCL, for its ink-jet printers in the 1980s. It became widespread with the introduction of PCL3 for the company’s popular LaserJet printer. PCL5 is the last version to be based on the traditional code that the computer driver sends to the printer to give it the instructions on how to print the page. PCL6, also known as PCL-XL, is a more powerful driver that operates completely differently, while retaining the PCL name.

Language

While HP considers both PCL5 and PCL6 to be printer command language drivers, each software uses different languages to deliver data to the printers. PCL5 and previous versions of the HP drivers use ASCII code to send the data and commands from the computer application to the printer. PCL6 compiles the pages from the computer application into a binary format before sending the package to the printer. The new binary language is more compact and offers additional features.

Functions

Up to PCL5, printer drivers have limited functionality. These drivers give commands such as for a new page or new paragraph and identify the fonts for the document. The resolution is usually fixed and limited to 300 dpi. Under PCL6, the driver can also address the requirements of images and graphics. It translates vector diagrams as well as bit maps, and can handle higher resolutions. Since they process complex graphics commands directly, the PCL6 drivers operate more quickly and generate less traffic.

Operation

The PCL drivers up to PCL5 use special characters to initiate commands, and send the text of the document to be printed as normal text. Printers respond to the special characters, usually prefaced by the character represented as “Esc” on a keyboard, by carrying out simple actions such as starting a new line. PCL6 is oriented toward printing color graphics as well as text. Such printing requires more complex commands, and plain text becomes less important. PCL6 takes commands from the operating system graphical user interface and translates them into commands for the printer. As a result, the printout more closely matches what the application shows on the computer screen.

Compatibility

HP includes all the commands from previous versions of PCL in the new PCL version. PCL5 is completely backward-compatible. PCL6 has a modular structure and, as such, doesn’t include the older commands the same way. Instead, HP added a module called PCL6 Standard to ensure backward compatibility. Because of the new structure, this compatibility is not seamless, and HP recommends addressing compatibility problems with PCL6 by replacing the driver with the latest PCL5 version.

joomla 1.5 set width of poll results dropdown select field

Jooimla 1.5 has a basic, but useful component built in to create basic polls. Theses polls can be used to gather information and feedback on anything you want.

Users can access the “Results” page and can see the results of all your polls by selecting the correct poll from the drop down box on the “Results” Page.

If you have a long question the drop down box cut’s the question and you can read the whole question of the poll.

To increase the size of the Poll drop down in the Poll’s “Results page…do the following

1. Go to /components/com_poll/views/poll/view.html.php
2. Make a backup of the file
3. Change the width value in the below code from 200px to whatever you want

// dropdown output
$lists = array();
$lists['polls'] = JHTML::_('select.genericlist', $pList, 'id',
'class="inputbox" size="1" style="width:200px" onchange="if (this.options[selectedIndex].value != \'\') {document.location.href=this.options[selectedIndex].value}"',
'url', 'title',
JRoute::_('index.php?option=com_poll&id='.$poll->id.':'.$poll->alias)
);

to

Joomla Beez_20 template: Fontsize – Limit Size Increases

When you use joomla and use the Beez templates you have a module which allows you to set the Font size to Bigger…Smaller or reset. I implement this feature into some of my own templates and websites and need to limit the max font size depending on the design.

In some cases the font becomes to bif for the design so you need to limit the max font size.

Find the following file within the Beez template: md_stylechanger.js

Look for the following code snippet:
function changeFontSize(sizeDifference) {
currentFontSize = parseInt(currentFontSize, 10) + parseInt(sizeDifference * 5, 10);
if (currentFontSize > 180) {
currentFontSize = 180;
} else if (currentFontSize < 60) {
currentFontSize = 60;
}
setFontSize(currentFontSize);
}

Change both the values to a lower number like 160. You are now setting the max size.

If you wanted to limit users to the smallest size then edit the two values below:

} else if (currentFontSize < 60) {
currentFontSize = 60;

I hope this helps!

Dreamweaver: The following translators were not loaded due to errors: ICERegions.htm

I tried to open one of my files (which I have worked on previously without any errors) and got the following error:

The following translators were not loaded due to errors:  ICERegions.htm:  has configuration information that his invalid.  Server Model SSI.htm:  has configuration information that is invalid.

I followed some advice to reset the workspace:

Go to Dreamweaver > Windows > Workspace layout > Reset “workspace name”

BUT it did not work.

The below solved the Dreamweaver translators were not loaded error for me:

1. Close Dreamweaver.
2. Open a Windows Explorer window.
3. In the Address bar enter %appdata% and click Enter.
4. Open the Adobe directory.
5. Open the Dreamweaver folder for the version of Dreamweaver you are using.
6. Dreamweaver CS4 users only – open the en_US directory.
7. Open the Configuration directory.
8. Locate the WinFileCache.dat file. There may be some other numbers appended to this filename.
9. Save the file somewhere as a backup just in case.
10. Delete the file from the Configuration directory.
11. Open Dreamweaver and try again.

Note: You do this at your own risk.

Hope this helps.
