MQP Electronics Ltd Closure Announcement

It is with regret we must announce that, after 35 years, circumstances force us to cease trading.

Our attempts to organise a continuation of the company have failed, as global increases in unnecessary bureaucracy have rendered a specialist company such as ours non-viable.

The final day that our office will be staffed is Friday 22nd December 2023.

Our website will remain open for a further 6 months, and the latest version of GraphicUSB will be available from the website during that period. We will attempt to perform bug fixes and test specification updates.

Our email addresses will also remain available during this period, so that we can reply to queries and bug reports.

We would like to thank all our customers for their past support.
