на сайте производителя был? там есть прошивка фирмвер, попробуй перепрошить, кроме того, там есть мануалы, вот что я там нашёл: 14.2 How to Assign Print Jobs to Printers via a Print
Server
You can assign print jobs (print data) directly to the printers via the
print server. The logical printer1 is used as default port.
Make sure that the logical printer does not convert data (e.g. ASCII to
PostScript), see: ������������189.
Print File Format The print file must be in a format that suits the printer. If necessary,
use the 'Print to file' function of your application software. When a
print file is downloaded to the print server, the file is automatically
recognized as print file and printed.
