Sending HPGL data to plot devices does not work anymore
A Windows 11 update released in early August 2026 has caused an issue with the output of plotter data from Grafis to HPGL-compatible plotters. Many customers have previously used the standard ‘Generic / Text-only’ printer driver included with the Windows installation and were able to send HPGL data to their plotter using the ‘WINSPOOL:’ shortcut in the Grafis Plotmanager or in the Grafis plot output. Typical devices for this output are e.g. the Summa S-Class, HP Designjet, Canon iPF, Canon TM 300, Epson SC-T5100N, Zünd G3 and several others. All versions of Grafis up to and including Grafis 26.0 Rel. 43 are affected, as is the Plotmanager up to V1.996.
To continue using this output method, Grafis must be updated to version 26.0 Rel. 43/A and the Plotmanager to at least version 1.997.

The GRAFIS software is updated via the standard update process.

Display problems in GRAFIS 25
GRAFIS 25.0 uses a new graphics output for all lines, points, texts and dimensions. This output can lead to problems on some devices, which are usually caused by faulty driver versions of the relevant graphics cards for Windows.
In detail, the following are affected so far:
- Windows 10 or 11 on computers with Intel Core i7 and i9 CPUs of the "Ultra" series
- Windows 11 running in Parallels on Mac computers
Symptoms can be:
- Incomplete display of the left pieces bar, fields remain empty or are displayed incompletely
- Line objects on the main window seem to freeze; Grafis remains operable, but no objects or changes are displayed
Starting with Grafis 25.0 Release 33, the new option "SmartView: Transfer display as bitmap" is available in the Grafis programme settings, tab "Options". If it is activated, it usually solves the above-mentioned problem.
Long start-up time of GRAFIS 25/26 with Parallels on M1/M2 or M3 Macintosh
If GRAFIS is to be used under Parallels running on a Mac with M1/M2 or M3 chip, very long start-up times can occur. Up to 30 seconds have been measured. If you are experiencing this problem, please contact our support team by email or telephone. You will then receive a customised version from us that starts much faster.
