However, I don't know if COM connections will even be selectable in your case since your PC doesn't have any to begin with. ***** program will print to the LPT port and Windows willĪutomatically redirect the job to the USB printer port. Then to associate that network name with an unused LPT port. This is a very specific scenario, but the following directions may work for you:ĭirectly from that link: The solution is to assign the USB-connected printer a network name, and If you tell me your printer model I can check what language it supports. PCL6 printers usually also support PCL5, but PC元 printers do not. Printers that do understand text need to support a language called PCL5.

They are mostly the low cost printers, especially inkjets but also some lasers. Printers that do this are called host-based printers, where the Windows graphics engine converts the page into dots on the paper, rather than letting the printer do the conversion.

Many USB-only printers do NOT understand plain text, and will just ignore it altogether. There is one proviso however - and it applies regardless of which method you use to get the data to the printer, hardware or software:Īs your program only knows about COM1, I assume it will send plain text to the printer. Here, pc_name is the name of the sharing PC, and printer_share_name is the share name you gave the printer when you set up the share.įrom then on, anything you send to COM1 will be re-routed to the printer. Now, start a command prompt and type: NET USE COM1: //pc_name/printer_share_name /persistent:yes Start by making the printer shareable (from Printer Properties > Sharing tab). Lee Harrison's link shows this command, but here's a short description. There is a simple way to do it using standard Windows commands.
