If the error message, Unknown device appears, this can indicate that there is not adequate power and the PC can not identify the printer correctly. Verify that there are no extension cables and that the power cable is no longer than five meters. Reseat the power cables.
Before sending your document to print, select Properties which will open your printer`s driver settings. Find the Paper Settings tab, this will allow you to select various media types that your printer can handle. Select your Paper Type. (Cardstock, Glossy Cardstock etc.)
HP recommends reading the documentation that came with your printer, including the owner`s manual or user guide, to find out what types of paper your printer can support. LaserJet and OfficeJet printers can typically handle card stock, though others may not.
Not all printers can print heavyweight cardstock. This can be further affected by paper grain.
If you see an “unknown accessory detected near you” message (or similar), it means there`s an item compatible with the Find My network that might be traveling with you. If so, its owner may be able to see your location. You should look to see if something you`re borrowing has such a device attached.

Insert the stack of paper into the product, and then gently push the paper guides snugly against the paper. Make sure that the paper is fully inserted into the product. Try printing again. If the issue is not resolved, try loading different brands of paper and different types of paper, one type at a time.
Cardstock: Cardstock printer paper is thicker than ordinary paper. Its thickness and durability mean it`s often used to create paper menus, postcards and invitations. Cardstock can be coated or uncoated, depending on the project.
You can achieve great printing results on quality, thick, heavy cardstock using an inkjet printer. And yes, you can save some money too! Inkjet printing is often an absolutely viable alternative to professionally designed, store-bought, and third-party printed cards.
Click on the drop-down menu under the “Paper type” or “Media type” heading. Select the “Cardstock” or “Matte” option — whichever paper type you have — to set it to the thick paper setting. Click “OK.”
If you are printing on paper over 200gsm, it is advisable that you use the bypass tray rather than a paper tray, as it passes the sheet on the straightest route through the printer, which will reduce the risk of paper jams, as the thick paper is less flexible than thin paper.
What is Card Stock? Card stock, sometimes spelled “cardstock”, is thicker and more durable than regular printer paper, but it`s thinner and more flexible than cardboard. This balance between durability and flexibility makes cardstock ideal for a number of crafting and design applications.
Open Device Manager. Right-click Unknown device and click Update Driver Software. Select the `Search automatically for updated driver software` option, then Windows will install the new driver automatically.
All devices on a network may be found using their IP address and MAC address. A device on the internet or a local network is identified by its specific IP address, which is unique. The MAC address is the physical address that identifies each device on a network.
It doesn`t slow down your computer as there are no processes or CPU activity associated with them. It adds clutter to Device manager and in general I would say that you should either remove them or fix them. But it won`t have an impact on performance.
Most 300gsm card printers are likely to have a manual feed option, or a bypass tray which allows the thicker card to pass through the printer withought being bent or folder around the twists and turns of the main paper path from tray to output.
Click Start, point to Settings, and the click Printers. Right-click the appropriate printer, and then click Properties. Click the Paper tab, and then click the paper size you want to use in the Paper Size box. Click OK, and then close the Printers folder.
It`s important to make sure that your copier/printer can handle your desired paper thickness. Standard, desktop printers typically can`t handle anything over 80# cover, while a multifunction copier with a bypass tray can usually handle 100+ pounds.
If the LabelWriter appears as Unspecified or Unknown in Devices and Printers on Windows, it usually means that the computer has not identified that device as a printer yet.
The problem of the printer icon not displaying in devices & Printers is frequently resolved by downloading and installing the most recent printer driver. If your printer drivers are out of sync, they may not function until you download and install the latest update.
